a recent addition to Winter Wall (none of my rock climbing books mentioned this climb, but I saw the route, and climbed it without knowing its rating). I found later on Mountain Project the name and grade of its climb.
It is located just right of "Post Moderate". The start starts with a little overhang, but it does get easier (it left more like 5.7 above it). There are anchors about 30 meters up, it is a bolted climb. The 2nd anchors are only about 15 meters higher.
