Waterfall Creek enters from river right near mile 77.6, cascading steeply from the Bighorn Crags into the Middle Fork just upstream of Impassable Canyon. Guides highlight the creek’s waterfall and hiking/exploration near the Big Creek pack bridge, where the Middle Fork Trail leaves the canyon. No separate Euroamerican mill or homestead narrative was required to explain the mapped POI; its significance is primarily scenic/geologic at the Impassable Canyon gateway.
