The M was created by students from Montana State University in 1915. It’s a bunch of rocks painted white. It has a couple of routes up the mountain. You can go to the right up the ridge on a steep trail that is less than a mile or you can travel to the left on a more gradual path that lasts 1.5 miles. In recent years, crews have added a few shortcuts through the timber. It’s only about ten minutes from Treeline and Wild Crumb to the parking lot at the base of the M Trail.
