Folks have been climbing at Baldwin since 1993. It is a beautiful dolomite cliff, about 3 miles in length, 15 miles outside of Lander. It's described in both Lander Rock by Collins and White, and Lander Sport Climbs by Bechtel. Baldwin Creek boasts the best rock and the highest concentration of hard clip ups in the Lander area. There are about 60 routes ranging from 5.10d to 5.14a with a few projects that will check in at 5.14 when they finally get done. The rock quality is exquisite, pocketed, 15 degrees overhanging and deceptively hard to read.
The downside? The cliff faces south, it's hot all the time and there's only 1 shade tree on the whole cliff. Oh, you'll also need a 4wd vehicle to get there and there's a 2 mile approach that sucks on the way out cuz its really uphill. Winter access is impossible as the road is closed around Thanksgiving.
Getting There
Leave Lander on the Baldwin Creek/Squaw Creek loop. Take a dirt road at the far end of the loop and start switchbacking up towards Shoshoni Lake. The road gets really bad at the top of the switchbacks. You park at a small pulloff near a kiosk and hike in on a faint trail from there.
