2023 Map of Thorn Lake

USGS Topo · Published 2023

About this map

Fort Rock Valley defines this arid landscape in central Lake County, where the topography transitions from flat basin floors to the steep rising slopes of Table Mountain. The map centers on a series of hydrological features unique to the high desert, most notably the seasonal waters of Thorn Lake and the aptly named Bottomless Lake. These basins, along with the Depression Sump, suggest the endorheic drainage patterns typical of the Oregon outback.
