Rock River Canyon Wilderness

From west to east, remote waterways Rock River and Silver Creek flow through 150-foot-deep canyons. The two canyons are separated by a broad, flat ridge and surrounded by relatively flat uplands. Second-growth northern hardwoods can be seen, alongside stumps from logging operations that denuded the area by the end of the 1930s. In spring, Rock River leaps about 15 feet over Rock River Falls into a pool, pouring into Ginpole Lake, a secluded 13-acre body of water bordered by canyon walls. The waters offer anglers the chance to fish for rainbow trout, brown trout, brook trout, coho salmon, and northern pike.
