To approach Dark Ebony, park at the Mineral Fork, 5.7 miles up Big Cottonwood Canyon on the S side of the road. Cross through the gate and follow the old jeep road as it winds it's way up into the open canyon. From here continue up into the canyon, cross over the creek and head up the E fork of the canyon, working through the trees until you hit the ridge. Finally, continue along until you find the entry and drop on it.
