Thanks to jess for adding this peak.
Mount Rearguard is 12,204 foot peak on the Hellroaring Plateau, directly opposite the Line Creek Plateau (home of the famous Beartooth Highway). The approach consists of a long, poorly-maintained mine road up the side of plateau. The road has many tight, unprotected turns, but on any given day you will find at least 2-3 other vehicles in the old parking lot at the top. High to the end of the trail leading from the parking lot (roughly 4 miles) and then head straight for the mountain across the saddle that bridges Moon and Sliderock Lakes.
The climb itself is a class 2, with possible class 3 spots if you accidently pick a slightly more challenging route. I have heard of winter ascents, and can see the possibility of such if a different route besides the mine road is taken. My conscience doesn't allow me to recommend driving it in the winter.
Use USGS Alpine-Mount Maurice topo for the best visualization.
