2010 Map of Big Lost River Sinks

About this map

Big Lost River Sinks define this hydrologically significant area of Butte County, where surface waters terminate in the volcanic basin. This 2010 survey illustrates the complex drainage system of the Big Lost River as it reaches its natural end point, including the distinct Dry Channel Big Lost River. The landscape is characterized by its drainage patterns rather than dense settlement, with a network of transit and utility corridors such as Pole Line Rd and W Monument Line Rd crisscrossing the high desert. To the east, Lincoln Blvd serves as a primary artery, while Mahogany Butte Rd and Cinder Butte Rd provide access to the surrounding geological features. For researchers, the map provides a precise look at the seasonal and terminal water features that have shaped the Idaho desert landscape and its modern infrastructure.
