Took the ridge route out from the St. Mary Peak trail. Three of us and a dog. Quite an enjoyable trip, though a long day with all the ups and downs. We decided that hanging out on the summit of the South Twin for awhile was a better use of our time than scrambling over to the North Twin. What a great hike!
Climbed with dog. Great fall day. Came up drainage from Big Creek (4.5 miles up trail). Repeated this route in July 2010 with son and friends.
My friend Jim and I climbed over Saint Mary Peak to the South Heavenly Twin. Re reached it just at out turn-around time so didn't follow the ridge to the North Twin in spite of the fact that it looked very doable and tempting. We decided to leave it for another day.
The Twins are remote and require plenty of stamina to reach and survive!
Hiked in K. Creek, up the fourth ridge and across N and S Heavenly, down the SW side, around the south, then back down the second drainage to K. Creek and back to the car. 11.5 hours. A tough day. 5.5 hours to the N. Heavenly summit, another 30 minutes to the S. summit, then almost 3 hours to get down that canyon! It's got some good brush in it. I found the whole high traverse to have nothing worse than class 3, provided one route finds reasonably well. I was solo in trail runners, and did not bring or desire a rope or technical gear.
Summited the South Twin via St. Mary. 10 hours from car-to-car. Would like to try the North Twin with a rope...the final push of the traverse looked a little sketch. Will be back in a month or two.
Some of the most beautiful country in all of the Bitterroot. One brute of an effort though. Up and down all day with a total of 5800' of elevation gain. The constant changing of gears makes this route hurt.
This route can be kept to a Class 3 by staying below the ridge between Saint Mary and the South Twin and then going up the back side (west slopes).
We were thwarted on our traverse attempt by unstable snow on the saddle between S. and N. Heavenly, Luke who was on lead, fell through a cornice up to his armpits, we tried to push on but kept breaking through. We missed a winter summit by one week on this one, though we climbed in full on winter conditions!
