2013 Map of Austin Butte

About this map

Bruneau Canyon dominates the eastern half of this high-desert landscape in Owyhee County, where the Bruneau River carves a deep, winding path through the plateau. This 2013 survey illustrates the dramatic elevation shifts between the canyon floor and the surrounding Bruneau Desert. Local landmarks such as Austin Butte and Twin Butte rise above the flat expanse, providing critical orientation points for those navigating the arid terrain. The map details a network of ephemeral water sources including Salvador Lake, Rock Lake, and White Lake, which are characteristic of this region's hydrology. Transportation across this section of the Idaho backcountry is defined by the Blackstone Grasmere Rd, which connects the high flats near Big Hill to the wider county road system. The confluence with the East Fork Bruneau Canyon near the eastern margin highlights the complex drainage system feeding the main river gorge.
