Hike south of the Grocery Store Wall until you come to the chimney. Proceed into the chimney until you reach the fork where it opens up. Now look straight up. This is the route. You basically climb out of the chimney using any means possible. It is a bit awkward but rather fun.
There are a couple usable trees to set up a top rope. You will need at least 10 foot slings. Try not to get any gear lost in the surrounding cracks.
