Like the rest of Castle Rock, this rock consists of sandstone, with routes ranging from 20 feet to ~60 feet in length. Climbing is primarily sport, though a mixed route and a few trad routes also exist. Toprope potential exists on all climbs, though setting up a top rope on the northern climbs deserves some caution due to the exposure on the top of Indian Rock.
You'll usually find this area in the shade, as it is surrounded by trees on all sides. The tops of many routes and the rock itself are usually in the sun.
Beware of broken glass in the footpaths on the lower climbs, especially in leaf piles. This glass is probably due to late nighters who feel that tossing their beer bottles is fun. Also, beware sticking your hands places you haven't seen if you're climbing a route for the first time, especially if it looks like the route hasn't been climbed in a while.
Getting There
Approach time: 3 - 5 minutes.

There will be a sign a short ways (like 50 feet) in stating (among other things) "Indian Rock .1M", Go past this sign on the trail which will head up the hill and gradually left. You will find Indian Rock on the right side of this trail jutting 30 feet out of the ground, and surrounded by small boulders.
Climb the arete on the right side of the South face, working mostly around the corner in the tall narrow pocket. The climb consists of a large juggy haul up an overhung section of the rock, with a fun reachy finish at the top. For the 12a finish, work up and well left from the fourth bolt, and it's 11c if you continue up the arete. Be mindful that even though you've climbed the first 10 feet of the climb, there is stall groundfall (or slabfall, ...[more]
