About this map

The Big Lost River meanders through this high-altitude landscape, defining the character of the Thousand Springs Valley in eastern Idaho. The settlement of Chilly serves as a central point in an area dominated by irrigation and topographic landmarks, including the prominent Chilly Buttes and the nearby Chilly Cem. Water management is evident through the presence of the Chilly Canal, which redirects flow through the valley floor to support the surrounding Barton Flats.

South of the river, the terrain rises toward Bartlett Point and Swensen Butte, overlooking the Swensen Basin. This area is connected by a network of ranch and mountain roads, such as Trail Creek Rd and Sage Creek Rd, which follow natural drainages like Rock Cr and Tulman Cr. These routes provide access to the various springs and creeks that feed the basin, illustrating the intersection of natural hydrology and rural development in Custer County.
