2013 Map of Poison Butte

About this map

Poison Butte rises as a primary landform in this high-elevation corner of Owyhee County, part of a landscape defined by volcanic buttes and deep river canyons. Along the southern edge of the sheet, the Jarbidge River cuts a sharp, winding path through the terrain, joined by the seasonal drainage of Dorsey Cr. One of the most intriguing historical waypoints is Post Office Crossing, a named location that suggests an established route across the high desert plateaus. The topography here is marked by significant elevations including Middle Butte, with the land organized into early 21st-century township and range sections. This 2013 survey reflects the modern management of this remote ranching and wilderness area, where traditional crossings and natural landmarks remain the primary points of orientation.
