2021 Map of Cooper Peak

About this map

Cooper Peak and Western Peak dominate the high terrain of the Roberts Mountains in this central Nevada landscape. The topography transitions sharply from the rugged peaks of the southern half of the sheet to the broad alluvial reaches of Denay Valley in the north. This high-altitude environment is defined by its drainage systems, where seasonal water sources like Pete Hanson Cr and Birch Cr flow toward the valley floor. Tonkin Rd provides the primary access route through the northern section, connecting the more open terrain with the steeper drainages of Pete Hanson Canyon. For those studying the hydrology of the Great Basin, the presence of isolated water sources such as Lower Dry Creek Spring and Upper Dry Creek Spring indicates the critical points of moisture that support the area's high-desert ecosystem.
