Mount Irvine (East Slope) is a 9 mile out and back trail located near Lone Pine, CA. The trail is primarily used for rock climbing and is accessible from June until September.
This is a great climb from the Meysen Lake Trail. At the end of the trail you veer to the right or north until you reach the east ridge then you follow it all the way to the summit. I also did Mt. Mallory to the south
