Custer was established in 1877. It lies along Yankee Fork Road southwest of the city of Challis, within the Challis National Forest.
In 1981, the community was listed on the National Register of Historic Places as a historic district. Although the district covers an area of 29 acres (12 ha), only seven buildings retain enough historic integrity to qualify as contributing properties.
Most of Custer is now included in the Land of the Yankee Fork State Park, which also includes the historic Yankee Fork gold dredge, nearby.
