"The Gilbert Creek Allotment Area is in the central western part of Lander County, Nevada, with very small extensions into Churchill County. It lies east of the New Pass Range and mostly west of Reese River. Most of the area drains north into Antelope Creek and thereby into the Reese River. Portions east of the Shoshone Mountains, represented in the survey area by Mount Airy and the Ravenswood highlands, drain directly to the Reese River. A small part of the area drains south into Smith Creek Valley"--Leaf 2
