2017 Map of Coglan Buttes NE

About this map

Lake Abert dominates the eastern landscape of this high desert region, its alkaline waters meeting a steep, rising escarpment. To the west, the rugged topography is defined by the deep incision of Coglan Canyon, which cuts through the volcanic geology of the northern Great Basin. The map details a transition from the stark shoreline of Oregon’s largest hypersaline lake to the higher elevations of the surrounding buttes. Surveyed by the U.S. Geological Survey, this sheet documents a largely uninhabited wilderness, focusing on the distinct landforms and drainage patterns that characterize this portion of Lake County. The lack of settlements or roads emphasizes the isolation of this salt-lake basin during the early 21st century.
