2010 Map of Arco Hills SE

About this map

The Big Lost River winds through this high desert terrain in south-central Idaho, creating a riparian corridor in an otherwise arid landscape. This 2010 survey shows the hydrological patterns of the river as it moves through the eastern Snake River Plain. The primary transportation artery through the area is the diagonal route of 20 26, which serves as a major connection point through the basalt-strewn plains. Local access is facilitated by primitive and secondary roads such as Big Southern Butte Rd and Adams Blvd, which provide pathways toward the prominent volcanic features located just beyond this quadrangle. The sparse infrastructure and lack of named settlements reflect the region's historical use for grazing and its proximity to federal scientific and desert land reserves.
