|E Wall (aka F & part of G Faces)
I didn't notice a crux. Climbing the thick flake near the top might be a little difficult for beginners. Also, you can climb up to the flake with different variations, making it harder or easier depending on how you decide to go.
The route is depicted in Boston Rocks guide but not described in words. It is the left-most route on E Wall. To get to the bottom of the route, climb up from the water's edge to a broad ledge (10+ feet wide). The route starts here, near the left corner.
Climb up and a little right towards the anchor. Below the anchor there's a thick flake; follow this to the top.
There's one bolt at the top near the edge, close to the thick flake at the end of the route. There is also a small but sturdy tree, about 5-10 feet back from the bolt.
