Early Dry Creek trails were first used by Bannock and Nez Perce Indians, trappers, and explorers. Montana gold trails began in 1864 as early freight wagons and stagecoaches passed by the Hole-In-The-Rock Stage Station north of Dry Creek. The Oregon Short Line Narrow Gauge Railroad followed, with tracks laid from Corrine, Utah, to Butte, Montana, through this area in 1879. Because of a lack of water, railroad officials relocated the Camas Roundhouse to the north and then developed the new town of Dry Creek in 1892, three miles south of the railroad terminus because of its rocky terrain. Around 1897, Dry Creek was renamed Dubois in honor of Fred T. Dubois, an early U.S. Marshall and well-known U.S. Senator. Later trails for opal seekers ran north to Spencer, Idaho, and modern routes made Dubois, Idaho, a crossroads, with Interstate I-15 running north to Montana and south to Utah, County Road A2 leading to Island Park and U.S. 20, and State Highway 22 going west to Craters of the Moon, Sun Valley, and Boise. Dubois also includes the Community Library Tourist Center, the Heritage Hall Museum, originally the St. James Episcopal Mission Church and placed in the National Register of Historic Places in 1993, and a historic Civil Defense cave 700 feet long north of town.
