Wiggins Wall, named for late local climber Earl Wiggins, is the biggest cliff in Red Rock Canyon (from the guide book). It's the second to last wall going south on the right side of the canyon. Very secluded and be prepared to hike up to it. Use the belay bolts on the routes, they 're a bit high, but it's basically just a class-3 hike to get there.
Getting There
You can reach the wall using the climber access path off the main canyon trail. Pretty much turn right just before you reach the Cave on your left and follow the trail up to a great shady area near some junipers. Watch out for the poison ivy plants out there though, they aren't too close to the trail, but you should still be careful.
