Granite Peak Professional Review and Guide
"A long, steep backpack to a traditional launching point for ascents of Montana’s highest mountain, Granite Peak—strictly for experienced, well-conditioned hikers. Of the two trailheads used for this hike (West Rosebud and Phantom Creek), the West Rosebud is more popular, mainly because it’s slightly shorter and cuts 400 feet of elevation gain off the approach to Granite Peak. The trails from both trailheads
lead to the same place—the saddle between Prairie View Mountain and Froze-to-Death Mountain.
And whether coming from the east or west, the trails are for rugged individuals. Just reaching the saddle where the two trails meet is a climb of 3,500 feet from Mystic Lake or 3,900 feet from East Rosebud Lake. Once at the saddle, turn southwest and follow a series of cairns around the north side of Froze-to-Death Mountain."
