While most climb around the observation tower area, there are lots of good problems lower on the mountain. The problems are very secluded, most days I don't see anyone besides the park ranger on my way in. The rock is Quartzite (I believe?) and quite nice, with a variety of holds from sweet jugs to very thin crimps. The rock is also quite strong, no breaks so far. Since it is on the side of a mountain some of the landings are a little sketchy (slanted downward and rocky) so a pad is a must in my opinion.
If you park at the ranger station simply walk away from the ski runs/chalets through the forest and you will find problems interspersed throughout. You can slog through the forest or take the road toward the observation tower and just break off to your left whenever you see some good boulders. If you are around the large reddish vertical slab you are in the vicinity of some good problems.
