Some friends and I developed over 20 routes in this zone in the mid-'90s to early aughts. I'll upload our topos once I find them, but we called it the Pump House Crag and it's way cool, filled with spiller finger cracks and fun, Red Rocks style, face climbs. If you live the area, you have to check it out, and if you're on your way to the Creek, it's worth a stop. Great camping too!
Yeah, John. This is the Red Rocks Simulator Wall, home to Arm and Hammer and the Rizalla's Crack. Someone added a random bolt near the top "Arm and Hammer"...noticed it a couple of years back, but it's still a classic. Reminds me of our hand-drilling, first ascent forays every time I lead it. It's still "yikes" all the way to the anchor!
