List of mountain peaks of Oregon
View on Wikipediafrom Wikipedia
This article comprises three sortable tables of major mountain peaks[1] of the U.S. State of Oregon.
The summit of a mountain or hill may be measured in three principal ways:
- The topographic elevation of a summit measures the height of the summit above a geodetic sea level.[2][3] The first table below ranks the 30 highest major summits of Oregon by elevation.
- The topographic prominence of a summit is a measure of how high the summit rises above its surroundings.[4][3] The second table below ranks the 30 most prominent summits of Oregon.
- The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation.[5] The third table below ranks the 30 most isolated major summits of Oregon.
Highest major summits
[edit]Of the highest major summits of Oregon, five peaks exceed 3000 meters (9843 feet) elevation and 28 peaks exceed 2500 meters (8202 feet) elevation.
Most prominent summits
[edit]Of the most prominent summits of Oregon, Mount Hood exceeds 2000 meters (6562 feet) of topographic prominence. Four peaks are ultra-prominent summits with more than 1500 meters (4921 feet) of topographic prominence and 12 peaks exceed 1000 meters (3281 feet) of topographic prominence.
Most isolated major summits
[edit]Of the most isolated major summits of Oregon, Sacajawea Peak and Steens Mountain exceed 200 kilometers (124.3 miles) of topographic isolation and Mount McLoughlin exceeds 100 kilometers (62.14 miles) of topographic isolation.

[edit]- ^ This article defines a significant summit as a summit with at least 100 meters (328.1 feet) of topographic prominence, and a major summit as a summit with at least 500 meters (1640 feet) of topographic prominence. All summits in this article have at least 500 meters of topographic prominence. An ultra-prominent summit is a summit with at least 1500 meters (4921 feet) of topographic prominence.
- ^ All elevations in this article include an elevation adjustment from the National Geodetic Vertical Datum of 1929 (NGVD 29) to the North American Vertical Datum of 1988 (NAVD 88). For further information, please see this United States National Geodetic Survey note.
- ^ a b If the elevation or prominence of a summit is calculated as a range of values, the arithmetic mean is shown.
- ^ The topographic prominence of a summit is the topographic elevation difference between the summit and its highest or key col to a higher summit. The summit may be near its key col or quite far away. The key col for Denali in Alaska is the Isthmus of Rivas in Nicaragua, 7642 kilometers (4749 miles) away.
- ^ The topographic isolation of a summit is the great-circle distance to its nearest point of equal elevation.

Overview
Physical Geography
Oregon's mountainous terrain encompasses a significant portion of the state's total land area, concentrated primarily in the western and northeastern regions, with the Cascade Range covering approximately 17%.[8] The Cascade Range, a prominent north-south spine, acts as a significant orographic barrier, creating a pronounced rain shadow effect that results in wetter conditions on the western slopes—receiving up to 100 inches of annual precipitation—and much drier climates to the east, where areas may see less than 12 inches per year. This topographic divide influences weather patterns, temperature gradients, and vegetation distribution across the state.[9][10][11] Key physical features of Oregon's mountains include glaciated summits in the Cascade Range, where remnants of Pleistocene glaciers persist on the highest peaks, contributing to rugged cirques and U-shaped valleys; fault-block structures such as Steens Mountain in the southeast, formed by tectonic uplift along normal faults; and lower-elevation coastal hills in the Coast Range, which rise modestly to around 4,000 feet and consist of uplifted marine sediments and volcanics. The state hosts more than 200 named peaks exceeding 5,000 feet in elevation, reflecting a diverse array of volcanic, tectonic, and erosional landforms shaped over millions of years.[12][13] These mountains play a critical role in Oregon's hydrology, serving as the primary source for major rivers including the Columbia, Willamette, and Snake, through high-elevation precipitation and snow accumulation. Snowpack in the mountains provides 70-80% of the summer water supply for streams and reservoirs, particularly in the Willamette Valley and eastern basins, where meltwater sustains irrigation, hydropower, and aquatic ecosystems during dry seasons.[14][15] Ecologically, Oregon's mountains span distinct zones from alpine tundra above 8,000 feet, characterized by sparse vegetation, lichens, and cushion plants adapted to harsh winds and short growing seasons, to montane forests below, dominated by conifers such as Douglas-fir, true firs, and ponderosa pine that form dense canopies supporting understory shrubs and wildflowers. These elevations foster biodiversity, including large mammals like Roosevelt elk and black bears, as well as endemic plant species such as the Cascade penstemon, with habitats providing corridors for migration and breeding.[16][17]Geological Formation
The geological formation of Oregon's mountain peaks is primarily driven by plate tectonics, with the subduction of the Juan de Fuca oceanic plate beneath the North American continental plate initiating the Cascade volcanic arc approximately 45 million years ago during the Eocene epoch.[18] This ongoing convergent boundary process generates magma that rises to form stratovolcanoes and associated andesitic lavas, shaping the prominent peaks of the Cascade Range. In contrast, the northeastern ranges, such as the Blue and Wallowa Mountains, originated from older accreted terranes—fragments of oceanic and island-arc crust that collided with and were welded to the North American margin between 200 and 100 million years ago during the Mesozoic era.[19] These terranes, including volcanic and sedimentary rocks, were deformed through compression and metamorphism as they integrated into the continent. Significant Miocene events further sculpted the landscape, notably the massive outpourings of the Columbia River Basalt Group between 17 and 6 million years ago, which blanketed vast areas and formed the elevated plateau underlying the Blue Mountains through subsequent folding and faulting.[20] In the Wallowa Mountains, uplift during the Jurassic and Cretaceous periods (approximately 200 to 66 million years ago) resulted from granitic intrusions into metamorphosed oceanic rocks, creating a batholith that exposed diverse lithologies and elevated the range.[21] Dominant rock types reflect these tectonic histories: the Cascades feature primarily volcanic andesite and basalt from subduction-related magmatism, while the Steens and Blue Mountains consist of thick basalt flows from flood volcanism.[22] The Klamath-Siskiyou region includes ultramafic peridotite and metamorphic schist derived from ancient oceanic crust and sediments. Pleistocene glaciation during the Ice Age, with the last major advance around 12,000 years ago, eroded and sharpened peaks like Mount Hood through cirque formation and U-shaped valleys.[23] The Cascades remain tectonically active, with Mount Hood's most recent major eruptions occurring in the 1780s to 1790s, producing lava domes and pyroclastic flows, and the potential for future activity persists due to ongoing subduction.[24] In eastern Oregon, faulting along the Steens escarpment drives continued uplift, contributing to the dynamic evolution of the ranges.[25]Major Mountain Ranges
Cascade Range
The Cascade Range forms the dominant north-south volcanic spine of Oregon, extending approximately 260 miles from the Columbia River in the north to the California border in the south. This segment of the larger Cascade Volcanic Arc hosts over 15 major volcanic centers, including prominent stratovolcanoes and shield volcanoes, shaped by subduction-related magmatism over the past several million years. The range features the state's highest concentration of peaks exceeding 9,000 feet, with at least 10 such summits—all of volcanic origin—clustered in its central and northern portions, contributing to its rugged, glaciated topography.[8][26] Among the most notable peaks is Mount Hood, Oregon's highest at 11,240 feet, a classic stratovolcano composed primarily of andesite to dacite lavas with a prominence of 7,706 feet, rising dramatically from forested lowlands near Portland. To the south, Mount Jefferson reaches 10,495 feet as a deeply eroded stratovolcano, its glacier-clad slopes marking it as the second-tallest in the state with 5,761 feet of prominence. The Three Sisters complex further south includes South Sister at 10,358 feet, an active complex volcano with recent cinder cone activity; North Sister at 10,085 feet, an eroded basaltic andesite shield; and Middle Sister at 10,047 feet, similarly shaped by Pleistocene volcanism. Lower but distinctive summits include Mount Washington at 7,797 feet, a sharp volcanic neck resembling a horn; Mount Thielsen at 9,184 feet, known for its jagged, lightning-rod-like spire formed by resistant quartz monzonite; and Three Fingered Jack at 7,845 feet, a dissected basaltic andesite shield volcano. The range encompasses around 20 major summits with prominence greater than 500 meters, emphasizing its volcanic diversity from intact cones to eroded remnants.[2][27][28] Glaciers persist on at least seven major peaks in the Oregon Cascades, influenced by high precipitation and elevation, with notable examples including the Eliot Glacier on Mount Hood, covering approximately 0.6 square miles as of 2004 and serving as one of the largest in the contiguous U.S. outside Alaska, though continuing to retreat due to climate change. Popular climbing routes, such as the Mazama Route on Mount Hood's south side, attract mountaineers via moderate snow and ice ascents, while the range's wilderness areas preserve old-growth Douglas-fir forests at lower elevations and vibrant subalpine meadows with wildflowers like lupine and paintbrush above treeline. These features underscore the Cascades' role in Oregon's hydrology and biodiversity, though ongoing glacial retreat highlights climate impacts.[29][30]| Peak | Elevation (ft) | Type | Prominence (ft) | Key Feature |
|---|---|---|---|---|
| Mount Hood | 11,240 | Stratovolcano | 7,706 | Eliot Glacier; Mazama climbing route |
| Mount Jefferson | 10,495 | Stratovolcano | 5,761 | Glaciers on multiple faces |
| South Sister | 10,358 | Complex volcano | 5,588 | Active cinder cone summit |
| North Sister | 10,085 | Shield volcano | 3,126 | Eroded basaltic andesite |
| Middle Sister | 10,047 | Shield volcano | 920 | Part of Three Sisters group |
| Mount Thielsen | 9,184 | Eroded volcano | 3,387 | Spire-like summit |
| Mount Washington | 7,797 | Volcanic neck | 1,447 | Sharp horn peak |
| Three Fingered Jack | 7,845 | Shield volcano | 1,445 | Andesitic dissection |
Northeastern Ranges
The Northeastern Ranges of Oregon encompass the Wallowa Mountains, Blue Mountains, and Steens Mountain, distinct from the volcanic Cascades due to their ancient, eroded granitic and basaltic formations shaped by tectonic uplift and erosion over millions of years. The Wallowa Mountains, often called the "Alps of Oregon," form a compact, rugged block approximately 40 miles long and 20 miles wide, featuring a granitic core intruded during the Cretaceous period amid older metamorphic and sedimentary rocks. The Blue Mountains extend over 100 miles across northeastern Oregon, characterized as a dissected basalt plateau primarily underlain by Miocene Columbia River Basalt Group flows, with subsidiary ranges like the Elkhorns adding structural complexity. Steens Mountain stands as a prominent 30-mile-long fault-block escarpment in the south, rising about 5,000 feet from the surrounding high desert through Miocene basaltic volcanism along a normal fault.[35][36][37][25] Prominent peaks in these ranges highlight their elevation and isolation. In the Wallowa Mountains, Sacajawea Peak reaches 9,842 feet as the highest summit, with nearby Matterhorn Peak at 9,826 feet and Eagle Cap at 9,572 feet offering dramatic profiles above glacial valleys. The Blue Mountains' loftiest point is Rock Creek Butte at 9,105 feet in the Elkhorn subrange, followed by Van Patten Butte at 8,734 feet, both rising sharply from forested plateaus. Steens Mountain culminates at 9,733 feet along its broad, shield-like crest, lacking a sharp summit ridge but providing expansive views over the Alvord Desert. These summits, forged from non-volcanic intrusive and extrusive rocks, contrast with the sharper volcanic cones elsewhere in the state.[38][35][1][39][25] Distinctive features define the landscape's appeal and ecology. The Wallowa Mountains host deep glacial cirques, such as those cradling Ice Lake at 8,166 feet within the Eagle Cap Wilderness, remnants of Pleistocene ice ages that sculpted U-shaped valleys and moraines. The Blue Mountains feature steep basalt canyons along rivers like the Grande Ronde, exposing layered flows and supporting diverse riparian habitats amid ponderosa pine forests. Steens Mountain's eastern escarpment drops precipitously to alpine tundra zones, blooming with wildflowers in summer and sustaining unique high-desert ecosystems above 7,000 feet. Sacajawea Peak stands out as a key prominence leader in the region, underscoring the ranges' topographic dominance.[40][19][41] Across these northeastern ranges, five peaks exceed 9,000 feet in elevation, including Sacajawea, Matterhorn, Eagle Cap, Steens Mountain, and Rock Creek Butte, contributing to Oregon's non-Cascadian high points. Approximately 15 major summits qualify with over 500 meters of topographic prominence, emphasizing the area's concentration of isolated, high-relief terrain suitable for wilderness protection and recreation.[1][35]Western and Southern Ranges
The Western and Southern Ranges of Oregon encompass the Coast Range and the Oregon portions of the Siskiyou and Klamath Mountains, which together form a diverse, lower-elevation zone parallel to the Pacific coast and extending into northern California. The Coast Range stretches approximately 200 miles along the state's western edge, measuring 30 to 60 miles wide with an average elevation of around 1,500 feet, primarily composed of sedimentary rocks from ancient marine deposits and volcanic basalts from Eocene-era eruptions associated with the Siletzia terrane.[42][43] These ranges lack the dramatic volcanic profiles of the Cascades, instead featuring undulating ridges and steep coastal escarpments shaped by tectonic uplift and ongoing erosion. The Siskiyou-Klamath complex, located in southwestern Oregon, covers rugged terrain with metamorphic cores dating back over 250 million years, including serpentine and marble formations from ancient volcanic arcs, and extends southward across the state border, spanning about 4,300 square miles in Oregon across Curry, Josephine, and Jackson counties.[44][45] Key peaks in these ranges highlight their boundary-spanning character and modest elevations compared to eastern Oregon highlands. In the Coast Range, Marys Peak stands as the highest summit in the central and northern portions at 4,097 feet, a prominent "sky island" supporting subalpine meadows and grasslands amid surrounding forests, offering panoramic views of the Willamette Valley and Pacific Ocean on clear days; the overall regional high point is Mount Bolivar at 4,319 feet in the southern Coast Range.[46][1] Further south, the Siskiyou Mountains feature Mount Ashland at 7,533 feet, the tallest peak in Oregon's portion of the range and a granite-cored massif within the Ashland pluton, with over 3,000 feet of topographic prominence that underscores its isolation.[47][48] The Klamath-influenced southern edges include shared transboundary summits like Preston Peak (7,309 feet, primarily in California but visible from Oregon trails) and Russian Peak (8,743 feet, marking the range's southern terminus). These ranges host only about five major summits exceeding 7,000 feet, with roughly 50 peaks surpassing 4,000 feet overall, emphasizing quality over quantity in their rugged profiles.[49][50] Ecologically, these ranges support temperate rainforests and conifer-dominated forests adapted to high precipitation and mild climates, without the glaciers found farther east. The Coast Range's coastal slopes harbor dense stands of Sitka spruce reaching up to 250 feet in height, alongside western hemlock and Douglas-fir in foggy, moss-draped canopies that receive over 100 inches of annual rainfall.[51] In the Siskiyous, diverse conifers thrive on serpentine soils, including rare Port-Orford cedar groves that can exceed 200 feet tall, alongside endemic species like Brewer's spruce, contributing to one of North America's most floristically rich temperate zones.[52][44] Steep ridges and deep canyons define the landscape, fostering biodiversity but also historical human activity, such as gold and chromite mining in the Klamath areas from the 1850s through the mid-20th century, which left legacies of altered watersheds and abandoned sites.[44] These features make the Western and Southern Ranges vital for ecological connectivity across state lines, supporting wildlife corridors and recreation amid their wetter, greener profile.Ranked Lists of Peaks
Highest Major Summits
The highest major summits of Oregon are those peaks exhibiting a topographic prominence of at least 500 meters (1,640 feet), a threshold that identifies independent summits rising significantly above surrounding terrain. This ranking focuses on elevation among such peaks, primarily those exceeding 8,000 feet (2,438 meters), with data derived from USGS topographic surveys and compiled by Peakbagger.com.[34] Oregon boasts 27 major summits above 7,500 feet (2,286 meters), predominantly in the Cascade Range but also including notable examples from the Wallowa Mountains, Blue Mountains, and Great Basin ranges.[34] Five of these exceed 10,000 feet (3,048 meters), highlighting the state's volcanic heritage in the Cascades, while others like Steens Mountain represent erosional uplifts in the east.[53] Elevations based on recent LiDAR data where available (NAVD88 datum). The following table presents the top 20 highest major summits, emphasizing elevation, location by range, and key access considerations.

Most Prominent Summits
Topographic prominence quantifies a mountain's independent rise above its surroundings, defined as the vertical distance from a peak's summit to the lowest contour line (key col) that encircles it without enclosing a higher peak, typically determined by connecting to its parent peak via the highest saddle. This metric emphasizes a peak's dominance relative to nearby terrain, independent of absolute elevation, and is calculated using methods like "clean prominence" based on USGS topographic data.[57] In Oregon, peaks with prominence of at least 1,500 meters (approximately 4,921 feet) are classified as ultra-prominent; the state features exactly four such summits, all exceeding 5,500 feet of prominence.[57] Oregon boasts numerous highly prominent peaks, with over 70 exceeding 2,000 feet of prominence, reflecting the state's diverse geology from volcanic Cascades to fault-block ranges in the east.[57] Among these, 20 peaks surpass 3,000 feet, including standouts outside the Cascade Range such as Sacajawea Peak in the Wallowa Mountains, which ranks second statewide despite its moderate elevation compared to taller Cascade volcanoes.[58] This ranking highlights how prominence elevates geologically isolated features like Steens Mountain—a massive fault-block structure in the Great Basin—above some higher-elevation but less independent Cascades peaks.[57] The following table lists Oregon's top 20 most prominent summits, ranked by clean prominence in feet, including elevation and primary range for context. Data is derived from standardized topographic analysis.[57]| Rank | Peak Name | Prominence (ft) | Elevation (ft) | Primary Range |

Most Isolated Major Summits
Topographic isolation quantifies the remoteness of a mountain peak by measuring the straight-line distance to the nearest point of equal or greater elevation, often the closest higher peak of significant prominence. In Oregon, this metric underscores the state's varied geography, from the clustered volcanoes of the Cascades to the expansive, arid basins of the southeast, where peaks rise dramatically from low-lying deserts. Major summits are defined here as those with at least 500 meters (approximately 1,640 feet) of topographic prominence, ensuring focus on independently rising features rather than minor spurs. Data for these rankings derive from Peakbagger.com, incorporating recent LiDAR and GPS measurements for greater accuracy.[59][6] Among Oregon's major summits, six exceed 50 miles of isolation, with the top two—Sacajawea Peak in the Wallowa Mountains and Steens Mountain in the high desert—standing out for their extreme separation, reflecting the influence of regional tectonics and erosion patterns that isolate northeastern and southeastern highlands.[59] Steens Mountain exemplifies this remoteness, rising over 5,000 feet from the floor of the Alvord Desert, a vast playa basin that amplifies its standalone character amid sparse surrounding topography.[60][61] These isolated peaks contrast with the denser Cascade clusters, where proximity to neighbors reduces isolation despite high elevations; prominence values for these summits, as detailed in the Most Prominent Summits section, further contextualize their structural independence.[59] The following table ranks the top 10 most isolated major summits in Oregon, including isolation distance, elevation, prominence (cross-referenced for scale), and primary range affiliation. All values are in feet and miles, sourced from verified topographic analyses.[59]| Rank | Peak Name | Isolation (miles) | Elevation (ft) | Prominence (ft) | Range Affiliation |
