The Jim Sage Mountains are a subrange of the Albion Range. The Idaho Encyclopedia (published by the Federal Writers Project during the Great Depression) originally designated this range along with the Cotterel Mountains as the Malta Range. Modern map makers have recognized that there are actually two separate subranges and adopted the Jim Sage and Cotterel names.
The Jim Sage Mountains sit in the rain shadow of the higher Albion Range and are mostly treeless. The range is bounded by Raft River Valley to the east and the Elba and Alamo valleys to the west. Elba Peak at 8,046 feet is the range high point. There are six other ranked summits in the range.
