Iargo Springs lies adjacent to River Road and has been used continuously since pre-settlement times as a drinking source. Tradition has it that government surveyors named the site in the 1840s, having gotten the name from the local Indians who used the location for tribal powwows. The Indians believed the springs held mystical powers. Europeans have visited the springs since the early 1900s. In the 1930s, the Civilian Conservation Corps constructed a trail to the springs and a rustic campground at the top of the bluff where the parking lot is now. The Forest Service plans to redevelop this side, restoring the atmosphere it once had.
