This 10 foot high boulder is some weird kind of granite/quartzite (Geologists??) and has some fun problems. Some of the holds are sharp and all the problems are standing starts.
For the Lonely boulder, head to the North (right as you come in) on an obvious trail. The boulder will be up and to the left after about 100 yards of hiking in (boulder is about 25 yards off the trail).
