Historical Sites
Mackay’s Mine Hill Tour
This self-guided tour features mines, headframes, sawmills and historic cabins around the Alder Creek Mining District. The Shay Railroad Trestle has been recently renovated. This district was active from 1879-1980 producing a million tons of gold, silver, copper, lead and zinc ore.
Challis Bison Jump
Early inhabitants of the round valley harvested bison at the nearby Challis Bison Jump. Archaeological excavations in 1970 provided a glimpse into the early use of bison. Several glass beads, many stone tools and points, and the bones of about 30 bison were located during the project. Follow the 0.25 mile paved pathway at the Land of the Yankee Fork Interpretive Center.

Custer Motorway
Traveling the Custer Motorway from Challis to Custer is a very interesting interpretive loop featuring historic sites, panoramic views and interpretive signs. Begin at the Interpretive Center near Challis, where displays tell the Yankee Fork mining story. Then, travel the old toll road where freighters and stages traveled to Custer and Bonanza.
Custer / Bonanza / Sunbeam
Beginning in 1870, these areas were booming with people set on finding their fortunes in gold . But the gold eventually played out leaving Custer and Bonanza ghost towns by 1911. Today, restored buildings and secluded cemeteries are all that remain. At Sunbeam, interpretive signs describe the beautiful Salmon River and the remnants of the Sunbeam Dam, which was breached in 1934.
