| Dipping rocks along Titus Canyon Drive in upper Titanothere Canyon are the Titus Canyon Formation interval of Late Oligocene age (about 28 million years). The lower green unit is a thick tuffaceous conglomerate and sandstone. The upper brown interval is mostly layers of volcanic breccia, tuff, and ash beds from volcanoes that erupted in the region early in the formation of the Great Basin geologic region (Reynolds, 1976). |
