1966 Map of Coglan Buttes NE

About this map

Lake Abert dominates the eastern edge of this terrain, its shoreline punctuated by numerous Springs and an expansive Alkali Flat. The map reveals a landscape defined by dramatic elevation changes, where the western heights descend steeply toward the water. Traces of early movement through this high desert region are visible in the form of the Old Hotchkiss Road (Jeep) and various Jeep Trails that skirt the base of the ridges. Near the shoreline, specific points of interest like a Cave and several bench marks, including BM 4257, indicate the survey's focus on the narrow corridor between the rising buttes and the lake. The incision of Coglan Canyon to the west suggests the primary drainage patterns of this arid environment during the mid-1960s and early 1980s.
