Little Lost River Sinks and Big Lost River Sinks define this high-desert basin in Butte County, marking the unique terminal drainage where surface waters vanish into the aquifer. The geography is shaped by the transition from the steep, ridged slopes of the Lemhi Range down into the expansive Little Lost River Valley.
