Lake Abert dominates the eastern expanse of this high-desert landscape in Lake County, where the steep fault-block escarpment of the Coglan Buttes meets the shoreline. The terrain is defined by dramatic elevation shifts, notably within Coglan Canyon, which carves through the volcanic uplands. This 2023 survey by the U.S. Geological Survey and BLM captures the stark geography of the Oregon Outback, characterized by its endorheic lake system and precise public land survey system grid lines. The lack of established settlements or road networks within this quadrangle reflects the arid, unsettled nature of this portion of the Great Basin, where land use is primarily managed for conservation and resource oversight.
