Once you get up the hill into the clearing there are 3 walls from small, to med, to large, starting from the far right moving to the left. The rock can crumble if you pull too hard but most edges and pockets should be fine to pull on. I have not checked out to see if you can top rope but there are many trees at the top that you could anchor off. The big wall to the left is probably your best bet for bouldering and possible top rope; at least 5 routes could be done on it.
If you are on the road near the rugby field you should be able to see it through the trees. If you head down to the water treatment plant, there is a creek and an old bridge. Cross the bridge and head up the left-side path to the clearing. It's a 5-min. hike or less. From there you will see the rock and choose what you want to climb.
This past Tuesday Feb. 21st, I went hiking back in the woods, and you could have a party up there in the clearing. Get a slackline going between some trees and have a good time bouldering (with spotters and pads please) and have some fun. I can not wait for the snow to be gone and a little warmer weather and I'm going to head up there for some afternoon climbing.
I used to go to UWP. I tried climbing and boulding on this rock in the past, and it's a bit crumbly. Do not sling 'trees' or bushes on the cliff. I had on pull out on me. The rock is to soft for pro. You may want to consider anchoring to the trees a ways back and top roping it. And yeah that little cut out is great for parties, but the cops do drive to the rugby field lot and look for light.
This thing might kill you if the Campus Police don't find an excuse to ticket you. I live within walking distance and I don't think its worth it. I saw about a 2 foot diameter chunk come off just from someone pulling on it.
