I climbed Castleton Tower for the first time back in December, choosing the 5.9 sandbag Kor-Ingels route and was pretty much dusted by the glassy calcite chimneys and off-widths. This time, @markdangelo and I decided to go up the North Chimney, an amazing 3-pitch route with a little bit of everything. It was supposed to be a warm day with just a bit of extra wind, but it ended up being 10m/s gusts accelerated by the wind tunnels. Mark forgot his puffy at the base and was freezing his ass off, so we ended up sharing mine at the top just to keep the stoke high. We shared the summit with Ben and Owen from Washington.
