Hotzenwald
The Hotzenwald is a landscape and region in the Southern Black Forest in the county of Waldshut. Its headquarters was the Waldvogteiamt.
The region of Hotzenwald is not precisely defined in the records. In a narrower sense the Hotzenwald is the southernmost region of the Southern Black Forest, bounded in the west roughly by the Wehra, in the north approximately by the upper reaches of the Alb River near St. Blasien, in the east by the hill ridge between the Alb and Schlücht rivers, and in the south by the High Rhine and Klettgau rivers. This definition of the Hotzenwald more or less covers the same area as the territory of the former County of Hauenstein.
In a wider sense, other regions may be counted as part of the Hotzenwald that were linked to St. Blaise Abbey or the County of Hauenstein, both of which were historically important in the Southern Black Forest. These additional areas include, for example, the parish of Gersbach (Schopfheim), which was first mentioned in 1166 by the gift of a church to St Blaise Abbey. This parish lies immediately northwest of the Wehra. Others include the regions in the northwest as far as the middle and upper reaches of the Wiese river and in the east to the hill ridge between Schlücht and Steina rivers.
Whichever definition is used, the region mainly covers the central and high areas of the Southern Black Forest. It climbs rapidly from the level of the High Rhine (about 300 m above sea level (NN)) up to heights of 500 to over 1,000 m above NN across the majority of the area. The region drops from the summits of the Southern Black Forest in the north to the High Rhine in the south and is characterised by sunny plateaux and high valleys.
The rivers in the Hotzenwald generally form high valleys in their upper reaches and cut deeply into the basement of the Black Forest rocks in their lower reaches. They follow the downslope of the Southern Black Forest from north to south before emptying into the Rhine as right-hand tributaries. The main rivers in the Hotzenwald region, from west to east, are the Wiese, Wehra, Murg, Alb, and Schlücht.
The parishes in the heart of the region are Rickenbach, Herrischried, Dachsberg and Görwihl.
The oldest rocks occurring in the Hotzenwald are gneisses and migmatites, which were formed in the Palaeozoic era. The largest part of the Hotzenwald is the granite countryside between Bernau and Bad Säckingen. The granite rocks that occur here are, according to research, up to 335 million years old. Other elements of the terrain are granite porphyry and lamprophyre. Near Laufenburg, the Kleiner Laufen rapids broke through the basement; today they are impounded.
In the eastern and southeastern Hotzenwald platform rocks cover the basement. According to field research in the area of Waldshut/Dogern this layer of bunter sandstone is an average of 15 metres thick and divided into three elements: the upper stratum of 8 metre thick Röt clays; beneath it a roughly 5 metre thick sandstone layer mixed with carnelian (the Carnelian horizon); and, at the bottom, above the basement, a roughly 2.5-metre-thick stratum of Mühl sandstone.
