2017 Map of Arco Hills SE

About this map

Big Lost River winds through the southern reaches of this landscape in Butte County, tracing a vital watercourse across the high-desert terrain. The topography is defined by broad alluvial surfaces and shifting elevation, most notably at Deadman Flat in the northwest corner. This 2017 survey by the U.S. Geological Survey captures the modern transportation corridor where U.S. Route 20/26 cuts diagonally across the quadrangle, serving as the primary link through this sparsely settled region. The map provides a precise layout of the Public Land Survey System, showing the township and range divisions such as t3n r28e and t4n r29e, which are essential for property research and understanding the historical grid of the Idaho interior.
