Our destination—and where we turned around—Devils Causeway is named for this ridge at 11,800 feet which brings chills to those who are afraid of heights. Just beyond Ron B. is a narrow section of rocky ridge with steep drops on both sides. Crossing it requires good balance and no fear. It affords the opportunity to return to Stillwater Reservoir via a different route, completing a loop trail. Click here to see a 360° view.
