Carderock-- Jam Crack (5.2)
The lower part of the route is not visible here, but it climbs a detached block in front of this face. Holds are small but abundant and good. The crack is the crux and feels a little harder than most 5.2's I've tried without a rope, but Carderock has a reputation for sandbag ratings.
Although I did this without a rope without trouble, there is enough exposure, especially on the crack, to warrant roping up, despite the rating. This would make a nice climb for trad training or introducing beginners to rock climbing on a toprope.
