I just wanted to introduce a friend's son to climbing at Stone and we climbed this first. I chose the unnamed line to the left of U-Slot and climbed straight up through the v- notch in the overlap. He climbed without any difficulty other than being a little short for the move up through the notch. Nice to be back at Stone.
I hate having to list this route under U Slot but it is not listed as a route anywhere, even though it has its own line. It is between the Block Route and U Slot and heads up to the overlap at the v shaped notch and on up to the tree ledge. The only protection is a placement at the midpoint and again at the overlap. Other than the fact that it is quite easy, I recommend giving it a try. The move through the v-notch is much easier than it looks.
We are practicing for something that is coming up and this is one of six single pitch climbs I lead today. I took the standard line on top of the arete and climbed through the overlap directly to the belay rings above. I used a single cam near the top of the arete and one just under the overlap and ran out the rest. From the top of the arete to the overlap, I only use the slab. I do not move left into the shallow crack as that makes it too easy. This is another excellent beginner route.
Again, I took the line to the the ledge that is located between the Block Route and the true line for U-Slot. I just aim for the v shaped notch in the overlap and blast through it. There is a good spot to place a cam about halfway up and I usually place another cam or two before making the move up through the v-notch but there isn't really anything else for pro. I would recommend going this way for those tired of the regular lines to the left and right.
I again took the line between the Block Route and U-Slot, up through the notch in the headwall. It was my mother's 57th birthday and the day's climb was her present. We climbed the Arch once on the tree ledge.
