On July 8 & 9, 2006 I assisted Kris Richardson with a climb of Mt Adams via the Mazama glacier carry-over route with 6,800 elevation gain (most of which is with your full pack.) We descended the south side route, taking advantage of a great glissade.
Driving directions: From Salem, drive north on I-5 to I-84 East to Hood River. Cross the Columbia River, turn left on Hwy 14 for 1.5 miles, then right on Alt. 141 which merges with 141 in a few miles. Stay north on 141 until reaching Trout Lake, about 23 miles from the Columbia River. When you arrive at Trout Lake, stay left at the Chevron Station. Go one mile to the USFS Ranger Station. for this cllimb we met at the Ranger Station where we registered for the climb , got our climbing permits ($15.00) and did a convoy to the trailhead at Cold Springs Campground. (Follow the signs for Mt. Adams Recreation Area, and to “South Climb” trailhead.)
