Route & General Observations

Skied out to Williwaw Lakes on Wednesday and encountered a shallow and talkative snowpack in the valley. Whumpfs every couple of minutes and a few sudden collapses. Like the rest of the Front Range right now, the bottom half of the shallow snowpack consists of big depth hoar. Didn’t see any natural activity but vis was not that great.
