Getting There 

Park as for Practice Rock and hike 100 feet up the road to a faint trail. Look for an old stone foundation wall and angle up and right to a large ledge below the Cornerstone cliff (5 minutes). One can also approach from the Bowling Alley by following the trail that angles uphill and north/west along the Tungsten Mine Shaft Cliff, angle downhill towards a gully and scramble up onto the ledge below the Cornerstone cliff (10 minutes).

Great area to tick off several routes in a couple of hours if its not too busy.

Actually, I'm not Dan but his cool chick, Jenelle. Many thanks to whoever repaired the chopped hangers at The Cornerstone. It's really a fine solid rock with 6 good routes for their grades. All can be done in a short period of time, even on your lunch break. The only slip in June - Aug. is that it is extremely hot. I recommend after 5pm or early morning. This is excellent choice for winter climbing and great for a mixed party of beginner and advanced climbers.

The routes here are fun enough, but at times it's tough to know exactly where the intended climbing lines are in relation to the bolts. It's very easy to find yourself wondering if you're using a hold that's "supposed to be" for a neighboring route. Still, a decent place to go to get a little climbing in.

Hey, so I think I lost my phone up here. If anyone picks it up and gets a hold of me, that would be awesome!

There were probably 4 okay routes here, unfortunately the squeezing of lines on this tiny crag kind of left me with a bad taste in my mouth... see Beta Photo.
