2020 Map of Bassey Creek

About this map

McKay serves as the primary landmark in this upland corner of Umatilla County, where the terrain is defined by the complex drainage systems of the Blue Mountains. The landscape is characterized by a series of high-elevation ridges and deep creek beds, including Calamity Cr in the northern reaches of the quadrangle. The map illustrates the rugged land-use patterns typical of this part of eastern Oregon, where isolated outposts and high-country waterways dictate the placement of local roads. While the area is sparsely settled, the topographic detail provided by the U.S. Geological Survey reveals the intricate relief of the basalt-rich plateau and its relationship to the seasonal flow of mountain streams.
