A manmade retainaing wall of plated concrete. Certainly not worth a trip on its own for anyone traveling through town, but it does offer some unique features and a chance to mix it up a bit and still do some climbing.
Every single crack on the wall can be protected with cams no bigger than .75", except for one crack that is short and 5.6. It can take up to a #3, but its not worth doing.
Bring a runner to clip into the reinforcement rails up top to TR or to rap off and clean your gear. Use your imagination.
The crux of all routes is at the very top.
The cracks range from easy to easy 5.6-5.9, but doing purely face climbing can bump it to mid .10s-.11s real quick.
On the 101 North from San Luis Obispo, turn left onto lower Stagecoach Road. Its the turn before you start gaining any major elevation. The wall is 50 feet in from the freeway and on the right.
I believe this area was discovered by Kristin McNamara and friends in 2005. Back then, most climbers used clean aid techniques to scale the formation. Good job on the FFA's. The area is undeniably classic.
