2020 Map of Inside Lakes

About this map

Jarbidge River carves a deep path through the southern plateau of Owyhee County, eventually bordering the wide expanses of the Diamond A Desert. This landscape is defined by its dramatic elevation changes, with the sharp contours of the Bruneau Canyon visible in the northwest corner. The interior of the high desert plateau is marked by a series of seasonal catchments known as the Inside Lakes, situated within the broader Inside Desert region. The mapping shows a vast, undeveloped territory managed under the Public Land Survey System, with township and range lines like t13s r7e and t13s r8e providing the only primary grid across the arid terrain. The map serves as a detailed record of the natural hydrology and topographical transitions of this high-elevation desert environment.
