This climb took me two tries and is a great way to fool around on the rock during a hot summer in New Hampshire. The crux comes close to the top about 20' off the water. The topout is solid and pretty secure although the time I fell was in the top lieback crack/arete.
I've been told the water is too deep to ever touch bottom but always be aware of your fall zone and scope it out before trying it.
The climb starts out on the big wedged boulder beneath the downstream bridge. Shoe up and chalk up on the boulder. Next, chimney down until you can get into a big horizontal crack. Traverse out over the the big pool of Agassiz Basin until you are out over the water. The route climbs up and heads through a small bush a few moves into the route. Once below the steep overhang, do some face moves heading right towards the arete. Lieback into the crack there and head towards the lip.
None. This is a deep water solo climb. Your only protection is water and your ability to swim.
