Erebus Canyon

From the junction of highways 178 (Badwater Road) and 190, drive about 10.7 miles east on highway 190 to the turnoff for Dante's View. Follow the signs to Dante's View, which is another 13.1 miles. From the Dantes View parking lot, start hiking north on the unsigned but obvious trail up the ridge. After 3.0 miles, fork left off the trail, continuing north on the ridge for a couple-hundred feet to the top of a small hump. This is the top of "Erebus Ridge," a west-facing ridge that is the approach for canyons Typhon4, Erebus, Purgatory, and Purgamal, and an alternate approach for Abysmal. Turn left and head west-northwest down Erebus Ridge for about .6 miles, descending about 900 feet. This spot is not very obvious, except the terrain to the right (north) finally looks reasonable, and there are now (after 14 years of canyoneering traffic) even signs of human foot traffic. Head down the slope to the north, into the drainage. This is an upper drainage of Typhon4. Head downcanyon in Typhon4 for a couple-hundred feet and then exit up the slope to the right (north). At the top of the ridge, turn right (northeast) and contour over to the next drainage. This drainage is the top of Erebus Canyon.
