Backbone Rock

In the early 1900s, when timber harvesting was a primary industry, a 20-foot thick hole had to be blasted through rock to accommodate the railroad. Now known as "the Shortest Tunnel in the World," after the blast and the track was laid, the train engine's smoke stack could not pass through. The tunnel's top had to be hand-chiseled to solve the problem. A recreation area offers camping, fishing, and rappelling, as well as hiking with one trail leading across the top of the rock, and the other taking you to the 45-foot Backbone Falls.
