Overview
Built in 1871, this National Historic Landmark housed about $75 million in gold and silver during its heyday. Gold discovered in the Wood River Valley, Boise Basin and Owyhee County created the need for a Federal mint or assay office in Idaho. The sandstone Assay Office operated until 1933 when it became the Boise National Forest headquarters. Today, it is home to the Idaho State Historic Preservation Office and the Archeological Survey of Idaho.
