About this map

Big Southern Butte dominates this high-desert landscape in Butte County, Idaho, rising sharply above the surrounding plain. This 2020 USGS survey reveals a terrain defined by volcanic features and critical water management in an arid environment. The isolation of the peak is underscored by the proximity of the Big Southern Butte Airport and a network of remote access routes like Cedar Big Butte Rd.

Water sources are carefully documented, showing the reliance on features such as Big Butte Reservoir, Big Butte Reservoir Number Two, and the ephemeral Big Lake. Smaller, high-elevation water points including Frenchmans Spring and Webb Spring are etched into the contours of the main butte, providing a detailed look at how the geography of the Eastern Snake River Plain was mapped for modern land management and aviation.
