Stewart Valley and the western foothills of the Cedar Mountains define this high-desert landscape in Mineral County. The settlement of Omco sits near the head of Omco Wash, a name rooted in the region's early 20th-century mining history. Water sources are critical landmarks in this arid terrain, with Stewart Spring, Wildrose Spring, and Poleline Spring distributed across the valley floor and mountain slopes. Drainage patterns are dominated by the extensive Finger Rock Wash, which is traced by the rugged Finger Rock Wash RD. This survey provides a precise view of the geographic isolation and natural water points that dictated movement and small-scale settlement in this corner of the Nevada desert.
