Geological panorama view of the mountains between Arosa and Lenzerheide, as seen from Parpan (from Studer 1837: Table 2). It illustrates Studer’s tectonic model of vertically upward movement of metamorphic rocks (pink mica schist, quartzite, gneisses, blue dots denote hornblende rich parts), which crosscut and eventually overflow their sedimentary cover (blue limestone, blue with red dots dolomite, light green gypsum, brown Bündnerschiefer). The dark green body just below “Pass nach Urden” is composed of serpentinite. For a more recent geological explanation of this section, the reader is referred to Roesli and Trümpy (1967)
