2010 Map of Poison Butte

About this map

Poison Butte rises as the central landmark of this high-desert landscape in Owyhee County, providing a topographical anchor in an area defined by its drainage systems. The Jarbidge River meanders through the western portion of the quadrangle, joined by Dorsey Creek near the southern boundary. A key point of historical interest is Post Office Crossing, a named intersection that suggests a point of connectivity in an otherwise sparsely populated region. This survey captures the essential hydrology and terrain of the Idaho-Nevada borderlands, documenting the few established access points and natural landmarks that define the local geography.
