About this map

Little Glass Mountain and the surrounding volcanic landscape of Siskiyou County are defined by striking geological formations in this recent century survey. The terrain is marked by expansive obsidian and basalt deposits, notably the Crater Glass Flow and the Tilted Rock Lava Flow, which illustrate the region's recent eruptive history. A series of distinct peaks and craters, including Pumice Stone Mountain, Paint Pot Crater, and Shastine Crater, punctuate the high-altitude topography.

Access to this remote backcountry is maintained through a network of Forest Service roads, such as Usfs 44 N 79 and the prominent Davis Rd, which bisects the quadrangle from north to south. These routes serve the high flats and craters, including Grasshopper Flat and the vicinity of Little Mount Hoffman. The map provides a detailed view of the named natural features that define this unique section of the Modoc Plateau, from Giant Crater in the south to Grouse Hill in the north.
