1998 Map of Little Glass Mountain

USGS Topo · Published 2003

About this map

Little Glass Mountain dominates this volcanic landscape, where geological history is written in obsidian and ash within the meeting point of the Klamath, Modoc, and Shasta Trinity National Forests. The map documents a territory defined by geothermal activity and timber management, featuring the expansive Crater Glass Flow and the jagged Tilted Rock Lava Flow. Cultural and industrial markers are sparse but significant, including the Little Hoffman Lookout perched for fire surveillance and various Pumice Mines that utilized the area's volcanic deposits. This 1990s revision captures the area's essential infrastructure, from the Bray Well to the specialized Gooseneck Mc Cloud Ranger District roads, providing a clear record of the high-country terrain before modern shifts in forest management.
