Cool pics and impressive wall, Dan. From the following description by Sean Jones of the Cat Wall, (and Clint's aerial), sounds like it's significantly bigger and further upstream from your pics. FYI, Sean descended further north from you guys, from around Squaw Dome.
"But it took so much longer to reach the bottom than we expected, with all the bushwhacking and rappels, that we were committed to climbing back out by a new route. We scoped an obvious line up what looked to be a not-so-big wall and started climbing at 4:30 p.m., knowing darkness would be upon us by 7:30. The line goes directly up the center of the largest south-facing wall opposite Balloon Dome, but slightly upstream, thus taking us back toward our approach descent. We named this wall the “Cat Wall.” But cracks that looked open from the ground pinched down in places and didn’t all connect. Our sweet 5.9 simul-climb and jog to the beer store turned into a thin- at-times, run-out, 1,400' 5.11c. We had no bivy gear, extra food, or other way out, so we had to focus and keep pushing. We managed everything onsight and topped out at 10 p.m. on a moonless night. Wearing shorts and T-shirts, with fading headlamps and no extra batteries, we ditched our gear and bushwhacked uphill for four hours, worshipping the car like a god, when we finally found it, and drove home, arriving just before sunrise. We named the route Heaven and Hell. The route name fits the entire canyon."
