Andy Gange, Stuart Johnson, and I headed up to the base of Hillmans, we cut over to below Duchess and made our observations. It was snowing s1/s2 and winds picked up substantially once above the tree line. There was about 25cm of fresh light density snow (fist hard) sitting on top of a stiffer (finger/pencil hard) 5cm ice crust most likely developed on 1/16/21 (Saturday evening). We performed a CT and ECT with the following results.
