A makhtesh (Hebrew: מַכְתֵּשׁ ([maχˈteʃ]), Hebrew plural: מַכְתְּשִׁים‎ ([ˌmaχteˈʃim] – Makhteshim) is a unique geological landform found primarily in the Negev desert of Israel and the Sinai Peninsula of Egypt. A makhtesh has steep walls of resistant rock surrounding a deep closed valley, which is typically drained by a single wadi. The valleys have limited vegetation and soil, containing a variety of different colored rocks and diverse fauna and flora. The best known and largest makhtesh is Makhtesh Ramon.

Etymology

[edit]

Although commonly referred to as "craters", these formations are "erosion cirques" (steephead valleys or box canyons). Craters are formed by the impact of a meteor or volcanic eruption, whereas makhteshim are created by erosion.[1]

The word makhtesh is the Hebrew word for a mortar grinder (מַכְתֵּשׁ‎).[2] The geological landform was given this name because of its similarity to a grinding bowl.

Geology

[edit]
The outer wall of Makhtesh Katan

Where a hard outer layer of rock covers softer rocks, erosion removes the softer minerals relatively quickly, and they are washed away from under the harder rock. The harder rocks eventually collapse under their own weight, and a crater-like valley structure is formed. In Negev and Sinai makhteshes, the hard rocks are limestone and dolomites, while the inner softer rocks are chalk or sandstone.[3]

The center of the Negev is dominated by northeast-southwest anticlinal ridges. The crests of four ridges host five deep valleys surrounded by steep walls. The upper half consists of hard limestone and dolomite, and the bottom is friable sandstone. Each valley, known as a makhtesh, is drained by a narrow river bed.[4]

Negev

[edit]

The Negev has five makhteshes: Makhtesh Ramon, Makhtesh Gadol, Makhtesh Katan, and two small makhteshes on Mount Arif, south of Makhtesh Ramon.

  • Makhtesh Ramon is exceptional as it is drained by two rivers (Nahal Ramon and Nahal Ardon). It is the largest makhtesh at over 40 km long, 2–10 km wide and over 500 m deep. The rocks in this makhtesh contain thousands of ammonite fossils, as well as volcanic and metamorphic rocks.
  • Makhtesh Gadol (Large Makhtesh). At the time of naming, Makhtesh Ramon was uncharted, and so this was thought to be the largest makhtesh, at 10 km by 5 km.
  • Makhtesh Katan (Small Makhtesh) is the smallest major makhtesh at 7 km by 5 km and was charted in 1942 by Jewish explorers.

Overview

Definition and Characteristics

A makhtesh is a distinctive erosional resembling a or , formed through the differential erosion of anticlinal structures in arid environments. It features steep surrounding cliffs, typically rising 200 to 500 meters high, that encircle a broad, flat-bottomed valley drained by a single narrow outlet, often a . These landforms are unique to regions like the Desert in and parts of the , where resistant caprocks of and dolomite overlie softer sandstones, leading to the collapse and exposure of the underlying strata. Key morphological characteristics include the exposure of vibrant, layered rock formations in a spectrum of colors due to the bare, soil-free walls and valley floor, which lack significant vegetation and reveal geological strata from various eras. Unlike impact craters or volcanic calderas, makhteshes originate purely from erosional processes acting on folded rock layers, resulting in an inverted relief where the once-protected interior soft rocks are exposed after the erosion of the harder overlying caprock. The valley floors are generally flat, filled with alluvial sediments transported through the single drainage point, emphasizing their role as closed topographic depressions. Typical dimensions vary, but makhteshes can extend up to 40 kilometers in length, 2 to 19 kilometers in width, and reach depths of 200 to 500 meters, creating dramatic, enclosed basins that distinguish them from open canyons or irregular fault-controlled valleys. This structure provides exceptional geological windows into ancient rock sequences, highlighting the interplay of tectonic uplift and prolonged fluvial erosion in shaping these features. For instance, the largest example measures approximately 40 km long, 2–19 km wide, and 500 m deep.

Distribution and Examples

Makhteshes are erosion cirques primarily concentrated in the Desert of southern , where the arid climate and specific geological conditions favor their formation, with additional examples extending to the in and analogous landforms present in southern Jordan's region. Only seven such formations are confirmed worldwide, all restricted to the , which emphasizes their regional and limited global occurrence due to the unique combination of anticlinal structures and differential erosion required for their development. Prominent examples include , the largest at approximately 40 km long and 2–19 km wide, situated in the central about 85 km south of at coordinates 30°35′N 34°49′E. HaMakhtesh HaGadol, or the Big Makhtesh, measures approximately 10 km by 5 km and lies near in the northern at 30°55′N 34°58′E. HaMakhtesh HaKatan, the Small Makhtesh, spans about 5 km by 7 km and is located in the northeastern near the at 30°57′N 35°11′E. Two smaller makhteshim are located on Mount Arif south of . These features were first systematically explored and named in the 1940s by Israeli scouts traversing the , with the term "makhtesh" derived from their mortar-like appearance; subsequent geological surveys by the Geological Survey after 1948 provided detailed scientific documentation.

Etymology

Origin of the Term

The term "makhtesh" originates from , where it denotes a mortar or pestle, a grinding tool used for crushing substances in a bowl-like depression. This linguistic root aptly describes the geological feature's characteristic bowl-shaped erosion , evoking the shape of an ancient grinding vessel. The word appears in the , specifically in 1:11, referring to a low-lying area or hollow in , highlighting early recognition of such topographic forms. For centuries, "makhtesh" has been employed by local Jewish communities in the region to name these distinctive features, drawing on longstanding observations of the terrain. The term gained formal recognition in Israeli geological studies during the , with early systematic documentation appearing in works by researchers such as Leo Picard, who examined formations including in publications from the 1940s onward. Picard's contributions, building on fieldwork in , helped integrate the local into scientific discourse within Israel's emerging geological framework. In Talmudic , "makhtesh" is interpreted to describe geological depressions, such as the area around , underscoring its cultural significance in ancient Jewish texts as a descriptor for sunken or bowl-like terrains. By the mid-20th century, the term entered international English-language geological unchanged as "makhtesh," preserving its Hebrew specificity rather than translating it to broader terms like "," to accurately convey the unique erosional morphology observed in the . This adoption reflects the feature's exclusivity to the region, distinguishing it from volcanic or impact s elsewhere. In geological literature, makhtesh formations are primarily described using the term "erosion cirque," referring to a steep-walled, bowl-shaped basin sculpted by prolonged fluvial and mass-wasting in arid environments, distinct from glacial cirques found in temperate or polar regions. This adaptation highlights how differential exposes resistant rock layers as elevated rims around a central depression, often within anticlinal structures, creating a unique to hyper-arid settings like the Desert. The nomenclature distinguishes makhtesh from true "s," which imply explosive origins such as meteor impacts or volcanic eruptions, to avoid misconceptions; instead, "makhtesh" is favored for its specificity, differentiating it from generic features like grabens (tectonic rift valleys) or calderas (volcanic collapse basins). This precision underscores the erosional rather than cataclysmic genesis of these landforms. Early scientific studies sometimes employed synonyms like "Ramon-type structure" to denote similar erosional depressions in the , particularly in reference to as the archetypal example. The term "makhtesh" entered international English-language geological discourse in the 1970s, coinciding with increased fieldwork in Israel's Negev region, and has since become standard in peer-reviewed publications to encapsulate this distinctive arid erosion morphology. Terminological evolution reflects a shift from popular media's "crater" label, which evokes dramatic extraterrestrial or igneous events, to the academically precise "erosion cirque" to emphasize sedimentary and tectonic processes without misleading analogies. This refinement aids in global comparisons, as analogous but smaller erosion cirques have been identified in other arid zones, though none match the scale or structural complexity of Negev makhteshim.

Geological Formation

Erosional Mechanisms

The formation of makhteshes begins with the uplift of anticlinal ridges, which exposes layered sedimentary rocks to erosional forces, followed by differential erosion that preferentially removes softer underlying strata. In the , hard carbonate rocks of the Group, such as limestones and dolostones, form resistant caprocks that overlie more friable s of the Kurnub Group (Lower ) and clastic/carbonate strata of the Arad Group (); the less resistant sandstone and Jurassic layers erode more rapidly, leading to the collapse of cliffs and the creation of steep, enclosing walls around the depression. Flash floods play a central role in deepening the makhtesh depressions through the incision of ephemeral rivers, which carve a single outlet that drains the basin and facilitates ongoing valley excavation. These high-magnitude, low-frequency events, occurring in the hyper-arid environment, mobilize sediment and erode friable beds, with peak discharges in watersheds like reaching up to 72 m³/s during extreme storms, progressively widening and lowering the floor over 10–20 million years. Wind erosion supplements fluvial processes by abrading exposed surfaces and contributing to the smoothing of slopes in the arid setting, helping reveal the colorful stratigraphic layers while transporting fine particles across the landscape. Erosion has been active since the epoch approximately 23 million years ago, with initial incision tied to uplift and stream reversal, and accelerated phases during wetter Pleistocene intervals that enhanced fluvial activity. Key evidence includes alluvial fans and conglomerate breccias at the base of the cliffs, composed of debris from repeated collapses, as seen in deposits within the craters.

Tectonic and Stratigraphic Context

Makhtesh structures are embedded within the Syrian Arc fold belt, a regional system of northeast-trending anticlines and folds formed primarily during compression between approximately 80 and 100 million years ago. This compressional regime, associated with the closure of the Neotethys Ocean and far-field stresses from African-Arabian plate interactions, induced shortening and inversion of earlier extensional basins along major faults, including the Ramon Fault—a prominent shear zone paralleling the axis of . The stratigraphic succession in makhtesh exposes a continuous record from Mesozoic to Cenozoic strata, with Triassic sandstones (such as those in the Saharonim and Gevanim Formations) forming the basal layers, overlain by Jurassic carbonates and clastics like the Ardon and Inmar Formations. These Jurassic units, dating to around 200 million years ago, contain fossils of marine invertebrates, terrestrial plants, and early reptiles, reflecting alternating shallow marine, lagoonal, and fluvial environments during the Early Jurassic. The sequence ascends through Cretaceous sandstones and shales (e.g., Hatira Formation) to Eocene limestones, providing a window into progressive platform sedimentation and periodic transgressions across the northern Arabian Plate margin. Key structural elements include the differential exposure of older rocks in the central depression, resulting from the protective role of a resistant —typically Albian-Cenomanian limestones and dolomites of the Hazera Formation—that shielded underlying softer layers from fluvial and aeolian erosion while allowing peripheral incision. Volcanic intrusions, manifested as radial basaltic and trachytic dikes and sills, punctuate the sedimentary pile, emplaced during magmatism around 110-120 million years ago in response to regional extension preceding the main folding phase. On a broader scale, the tectonic evolution of makhtesh is modulated by the sinistral fault system to the east and the Red Sea-Gulf of rifting to the south, which have driven Negev uplift since the at rates of 0.1 to 0.5 mm per year, enhancing incision and exposure of the folded strata.

Specific Locations

Desert

The Desert in southern hosts several prominent makhteshim, unique erosional landforms that showcase the region's complex geological history. Among these, stands as the largest, extending approximately 40 kilometers in length and featuring steep, alpine-like cliffs that rise dramatically around its elliptical basin. This makhtesh is traversed by internal roads, including segments of Highway 40, allowing access to its diverse terrains while preserving its natural structure. Distinctive volcanic plugs and vents, composed of trachybasaltic and basaltic materials, punctuate the landscape, remnants of ancient magmatic activity from the period. Additionally, the area preserves fossils, including marine reptiles and ammonites, embedded in its sedimentary layers. Adjacent to Makhtesh Ramon and forming part of the Yeruham area's geological cluster are the smaller HaMakhtesh HaGadol and HaMakhtesh HaKatan, which measure about 5 by 10 kilometers and 5 by 7 kilometers, respectively. These adjacent makhteshim share a common drainage system, channeling water through interconnected wadis that link them hydrologically. HaMakhtesh HaGadol is renowned for its vibrant exposures of Nubian Sandstone, colorful Lower Cretaceous strata that reveal layered sandstones rich in heavy minerals and fossilized plant remains, providing insights into ancient desert environments. In contrast, HaMakhtesh HaKatan remains notably isolated, with minimal human impact due to limited access and its remote position, preserving a pristine erosional basin surrounded by high cliffs. Two even smaller makhteshim are located on Mount Arif, south of , contributing to the total of five makhteshim in the . Collectively, these sites constitute the "Makhteshim Country" cluster, a interconnected network of cirques spanning roughly 500 km², bound by northeast-southwest trending anticlinal ridges and systems that facilitate shared and patterns. This region exemplifies the Negev's tectonic and erosional dynamics, with the makhteshim drained primarily eastward. In modern times, the area is safeguarded within managed by the Nature and Parks Authority, including the expansive , which features dedicated geological trails for educational exploration and promotes conservation of its unique landforms.

Sinai Peninsula and Jordan

In the of , makhtesh-like erosional s form part of the Syrian Arc fold belt, exhibiting similar anticlinal structures to those in the but influenced by regional and stratigraphy. Notable examples include Gebel Maghara, a large feature approximately 60 km long, 20 km wide, and 200 m deep, characterized by resistant and dolomite caps overlying softer , , and layers, with a central resistant ridge partially obscured by sand dunes. Smaller instances, such as Gebel Hallal (8 km long, 6 km wide, 200 m deep) with over marl, , and disrupted by faults on its southern margins, and Arif en Naqa (4 km long, 2 km wide, 60-200 m deep) featuring atop marl and along a fault line, demonstrate partial exposures akin to anticlinal erosion on the Tih Plateau, where elevated chalky terrains up to 1,626 m experience deep dissection but lack fully enclosed basins. Near the Israeli border, smaller erosional depressions like those in the Elot area exhibit compact forms with exposed fossils from Eocene , highlighting marine depositional histories in this hyper-arid zone receiving less than 50 mm annual precipitation. Across the border in , geological features resembling makhteshim occur within the sandstone-dominated landscapes of the Arabian-Nubian Shield, though they are not formally classified as such due to drainage patterns or lithological differences. The Tzwilch structure in northern , part of the Syrian Arc, spans 13 km long and 5 km wide with depths up to 250 m, formed by dolomite and over , but is breached by two parallel streams, preventing the typical single-wadi drainage of true makhteshim. In , towering cliffs and narrow gorges result from differential erosion of Nubian Sandstone formations, creating mesa-like massifs up to 800 m high with blocky rock falls along vertical joints, evoking the steep-walled enclosures of makhteshim amid red desert sands. Similarly, the near the Jordanian border features a horseshoe-shaped erosional basin flanked by 300-500 m cliffs of and s, historically described as a makhtesh-like form with a central elevated magmatic core, integrated with ancient sites dating to the period. These cross-border sites share tectonic origins in the Syrian Arc's compressional folding but differ in environmental context: Sinai's examples endure extreme hyper-desert aridity with minimal vegetation and dune infill, contrasting Jordan's slightly more dynamic systems supporting sparse and Nabatean ruins embedded in the landforms, such as petroglyphs in 's cliffs. Access to Sinai features remains restricted due to ongoing geopolitical tensions and military zones, limiting fieldwork since the 1980s peace accords, while Jordan's analogous structures, including , have been UNESCO-protected since 1985, facilitating conservation amid tourism pressures.

Ecology and Biodiversity

Flora

The flora of makhtesh environments, such as in Israel's , consists primarily of xerophytic shrubs and succulents adapted to hyper-arid conditions, with sparse overall coverage typically below 5% of the ground surface. Dominant species include the salt-tolerant Anabasis articulata, which forms low woody structures up to 60 cm tall and thrives on saline substrates, and the fleshy-leaved Zygophyllum dumosum, a chamaephyte that exhibits preferential growth on upslope positions in erosion cirques. Scattered trees like raddiana (a subspecies of Acacia tortilis) serve as in bottoms, providing shade and habitat despite the low annual rainfall of 50-100 mm, which limits biomass accumulation and favors drought-deciduous growth strategies. In total, approximately 150 species have been recorded in , with about 65% being annuals that complete their life cycles rapidly during brief wet periods. Vegetation exhibits distinct zonation patterns influenced by , substrate, and within the cirque structure. On the upper rims and cliff faces, crustose lichens dominate exposed rock surfaces, forming biological soil crusts that stabilize slopes and contribute to in areas receiving less than 100 mm of annual . Ephemeral annuals, such as various and , appear transiently on rims following winter rains, exploiting short-lived moisture before . In the saline bottom conglomerates, halophytic species like Anabasis articulata prevail, tolerating high from evaporative concentration in the basin's depositional areas. Long-term dynamics of these communities have been monitored through permanent plots in since 1990, revealing significant population fluctuations over more than 30 years, driven by interannual rainfall variability and herbivory, with perennial shrubs showing resilience through seed banks and vegetative resprouting. Unique adaptations among makhtesh flora enable survival in this episodic environment, particularly for geophytes that endure flash floods in channels. Bulbous perennials like Bellevalia desertorum, an endemic species to the central and deserts, develop shallow root systems during early growth phases to access sporadic , while their underground storage organs protect against and flood scouring. These geophytes, including relatives like Asphodelus ramosus, benefit from ancient terrace structures that mitigate flood velocities, allowing persistence in flood-prone zones where surface flows can reach destructive intensities after rare storms. Fossil flora preserved in the sedimentary layers of provides evidence of past wetter climates, contrasting sharply with modern aridity. The Early Bajocian Inmar Formation yields remains of thermophilic ferns such as Piazopteris and abundant bennettitalean cycadophytes like Nipponoptilophyllum and Banatozamites, indicating a paratropical with mild seasonality and higher moisture availability during the . These assemblages, dominated by xeromorphic leaf forms suggesting periodic stress in tidal flats, highlight a paleoenvironmental shift toward the current hyper-arid regime over geological time.

Fauna

The fauna of makhteshes, particularly in the Desert's , is adapted to extreme aridity and rocky terrain, with approximately 40 mammal species recorded across reserves, many exhibiting nocturnal behaviors to avoid daytime heat. Prominent among these are the (Capra nubiana), which inhabit steep cliffs for foraging and predator avoidance, with significant populations observed around . Other mammals include red foxes (Vulpes vulpes), known for their opportunistic scavenging in desert wadis; Blanford's foxes (Vulpes cana), small nocturnal predators sighted in rocky areas near ; Arabian wolves (Canis lupus arabs), which range widely in the for hunting smaller prey; and occasional leopards (Panthera pardus nimr), with rare sightings reported in the vicinity as late as 2007. Reintroduced contribute to the , including the Asiatic wild ass (Equus hemionus, or ), released in starting in 1983 with a growing estimated at over 100 individuals as of the early 2000s, and the (Oryx leucoryx), reintroduced to reserves including areas around makhteshim to restore historical desert communities. Birds and reptiles contribute to the vertebrate diversity, with rock doves (Columba livia) commonly nesting on cliffs and Tristram's serins (Crithagra xanthopygia) foraging in sparse vegetation during breeding seasons in the Ramon Crater. Reptiles such as agamid (e.g., Trapelus species) thrive on rocky bottoms, utilizing basking sites for in the Negev's hyper-arid conditions, while vipers like the Saharan horned viper () ambush prey in sandy depressions within makhteshes. Invertebrates include scarab beetles (), which emerge in ephemeral pools formed after rare rains, feeding on in these temporary habitats. Biodiversity hotspots occur in internal wadis, where flash floods following events temporarily boost faunal densities by creating pools and flushing nutrients into the system. Makhtesh cliffs also serve as landmarks for routes, with raptors and passerines funneling along the Ramon Crater's edges during seasonal passages. Population monitoring in reserves like has documented recovery in herds, attributed to protections against overhunting that caused pre-1990s declines, transforming the species from locally endangered to a conservation success in .

Significance

Scientific and Geological Importance

Makhteshim function as exceptional natural laboratories for geological research, enabling detailed investigations into processes, stratigraphic sequences, and tectonic activities that have shaped arid landscapes over millions of years. Their unique morphology—deep, erosional cirques exposing continuous rock layers from to —facilitates the study of differential rates and structural folding within the Syrian Arc system. Hundreds of peer-reviewed papers have documented these features, highlighting their role in understanding formation through volcanic and sedimentary interactions, as seen in the eruptive breccias of associated with . Paleontological discoveries in the makhteshim have significantly advanced knowledge of life, particularly in , where well-preserved fossils reveal diverse marine and terrestrial ecosystems. Key finds include archosauromorph reptiles such as Tanystropheus species, indicating early diversification of long-necked aquatic predators along ancient coastlines. marine reptiles, including elasmosaurid plesiosaurs from the Menuha Formation, provide evidence of the Tethys Sea's faunal assemblages, while chondrichthyan remains underscore the region's role as a hotspot for studying vertebrate evolution. These exposures, free from overlying sediments, allow for precise stratigraphic correlation and have yielded insights into during periods of global climatic shifts. Research on Jurassic flora from the Inmar and Ardon Formations in offers critical paleoecological data, reconstructing humid subtropical environments that contrasted with the modern hyperarid . Fossil assemblages dominated by ferns, cycadophytes, and suggest warm, wet conditions conducive to lush vegetation along paralic settings, informing models of paleoclimate and paleogeography in the northern margin. These findings contribute to broader understandings of ancient atmospheric CO₂ levels and floral responses to tectonic uplift. Additionally, the makhteshim's erosional dynamics serve as analogs for arid landscape evolution worldwide, with comparative studies identifying similar formations in other tectonic settings and influencing global geomorphological models. Ongoing studies, initiated by the Geological Survey of Israel (GSI) in the late 1940s and closely tied to Hebrew University collaborations since the 1950s, have produced seminal publications on fault dynamics and structural evolution. GSI-led projects have mapped rift-margin tectonics and dike emplacement in , revealing radial basaltic systems that illuminate stress fields and fluid migration along faults. These efforts, spanning decades, emphasize the makhteshim's value in assessment and analogs. The Makhteshim Country's proposed World Heritage status, placed on the Tentative List in 2001, underscores its international scientific significance.

Tourism and Conservation

Makhtesh Ramon serves as the primary tourism hub among Israel's makhteshes, attracting visitors to its expansive erosion cirque through dedicated infrastructure like the Makhtesh Ramon Visitors Center, which offers exhibits on the site's geology and history. trails traverse the crater's diverse terrains, including ridges and dry riverbeds, while its Mars-like landscapes—rocky, red-tinged hills used for planetary simulations—enhance its appeal for adventure seekers. The site drew approximately 300,000 visitors annually as of 2017, supporting activities such as stargazing under its International Dark Sky Park status and guided off-road tours that explore remote sections. These unique landscapes, resembling extraterrestrial environments, significantly contribute to visitor interest across makhteshes. Tourism in bolsters , providing economic benefits to the region by generating in hospitality, guiding, and related services within , a town of over 5,000 residents overlooking the crater. Guided geological tours, emphasizing the site's formation and , have been a fixture since the late 1980s, following government initiatives to position as a center. Conservation of makhteshes falls under the management of the Israel Nature and Parks Authority, which oversees as part of Israel's largest to protect its geological and ecological integrity. Key challenges include damage from off-road vehicles, which erode sensitive soils and disrupt habitats, prompting stricter access regulations to balance recreation with preservation. , such as certain non-native plants in the , pose additional threats to native and , while conservation efforts address pressures like .
