I climbed here a few times when I traveled to the D.C. area on business. I got the local guidebook from REI, and headed out, thinking I was going to have a fun time on some easy solos. Wrong! Damn that rock is slippery! And yes, I spent a lot of time cleaning my shoes.
I stopped by after a morning of hiking and scrambling over at Great Falls to check this place out for the first time. I ended up soloing 5.2 Jam Crack, 5.3 Chockstone Chimney, and 5.1 Laundry Chute. I thought Jam Crack felt about right, but except for maybe one part of Chockstone, I thought it was easier than 5.3, and Laundry Chute seemed a little harder than 5.1. I also climbed something unnamed next to Laundry Chute, and that one was a bit harder.
It's a little harder climbing unroped here because the area is compact and it's tricky to stay out of the way of roped groups at times.
