I don't know if this climb has a name or who has the first ascent. I'm adding it because no south-facing routes have been added.
This route can be seen from the parking lot. Cross the tracks, and follow the chain link fence on the right (that surrounds the tunnel and the small man-made stream) toward the flow. You'll be heading towards the south facing wall of the canyon at this point. The fence ends but keep going up the hill until you get to the climb. Snowshoes would have been really great. It's about an 15 minute hike from the tracks to the base of the route. Hike up around to the right to set up a toprope.
A short but fun climb. On the left side, there seems to be more of a vertical pillar to climb. The middle isn't as steep as the pillar, and the right is thin and offers some mixed climbing.
