Trail Information
Rumors of placer gold drew miners into the area in 1876. They constructed the upper portions of the trail, used by geologist Clarence Dutton several years later. Crews built the present trail into Tapeats Creek in 1926. Thunder River, one of the world’s shortest rivers, flows for only 0.5 mile (0.8 km) before entering Tapeats Creek.
Variation
Once in Surprise Valley, the Deer Creek Trail branches west (right) into Deer Creek Valley. Entering a deep narrows, the trail traverses a ledge on the west side. Leaving the narrows, it descends a talus slope to the base of the waterfall and the Colorado River.
