Challis Bison Kill Site


Early inhabitants of the Round Valley acquired bison at the nearby Challis Bison Kill Site.  Archaeological excavations in 1970 provided a glimpse into the early use of bison.  Several glass beads, many stone tools and points dating to a wide variety of time frames, and the bones of about 30 bison were located during the excavation.  Learn more about the history and use of the Challis Bison Kill Site along the .25 mile paved pathway at the Land of the Yankee Fork Interpretive Center.  More information about the site is found inside the center.


Custer/Bonanza


These two sister cities were once booming with people set on finding their futures in gold.  Beginning in 1870, the area attracted gold seekers searching its streams and mountains.  Within six years, the mining communities of Custer and Bonanza sprang to life.   The 1880s brought rapid growth to the region as the Lucky Boy, General Custer and Montana mines produced abundant ore and the town of Custer reached a population of 600.  But the gold eventually played out leaving Custer and Bonanza ghost towns by 1911.  Today, restored buildings, the tales of the miners and secluded cemeteries are all that remain.  Take a guided or self-guided tour through the remains of this once thriving community and get a unique glimpse of turn-of-the-century gold mining.  Try your luck at the gold panning station.  Here you will learn about some of the colorful characters of the Yankee Fork such as Sammy Holman and Lizzie King.  Plan to join us in July as we celebrate Custer Day.  

Camping within and nearby the historic area can be found at National Forest, BLM and private campgrounds.  Camping opportunities range from primitive to RV hookups and B&B’s.  The elevation at Custer is 6500’.

Yankee Fork Gold Dredge/Sunbeam Dam 


Near Custer and Bonanza is the Yankee Fork Gold Dredge, a 988-ton monster barge that searched the gravels of the Yankee Fork for gold as recently as 1952.  During its operation it “mined” 6,330,000 cubic yards of stream gravel, leaving behind 5 ½ miles of dredge tailings and recovering an estimated $1,037,322 in gold and silver at a cost of $1,076,100.  Guided and self-guided tours are available during the summer.  At Sunbeam, interpretive signs describe the beautiful Salmon River and the remnants of the Sunbeam Dam, the only dam ever constructed on the Salmon.  The dam was built in 1910 to generate electricity for nearby mines.  The operation went bankrupt in 1911 and the dam was breached in 1934.  

Custer Motorway  


Traveling the Custer Motorway from Challis to Custer is part of a very interesting 90-mile interpretive loop.  Begin your adventure at the Interpretive Center near Challis, where displays tell the Yankee Fork mining story in a building styled after the old mining mills.  Then, travel the Custer Motorway where fees were once collected along the old toll road from freighters and stages on their way to Custer and Bonanza from Challis.   Work completed by the CCC in 1933 changed the old toll road to the Custer Motorway.  This backcountry road features historic sites, panoramic views and interpretive signs.  Note:  Travel on the gravel Custer Motorway portion of the loop is not recommended for trailers or low-clearance vehicles.  The motorway is open seasonally; please check locally for current conditions.  The highest elevation along the motorway is 8800’ at Mill Creek Summit.
