Hiked the cathedral lake summer trail in approach shoes up to 8k. Little snow existed on trail. Ski pen was 10cm when skiing SE chute at 10:30. Perfect spring conditions exist on southern aspects with appropriate timing. 

Photo 1: Two things to mention in this photo. First, you can see old avalanche activity from the January 24th - 25th cycle. Second, a great representation of how different snow surfaces can be from NE to SE. (Cold snow N, corn snow S)

Photo 2: cathedral bowl - notice how large these cornices are despite low snow year.
