Snow Characteristics Comments

Snow was a bit punchy, especially lower in the bowl where you'd sometimes sink into weak sugary snow below 4F slab from the weekend storm. Could easily find weaker underlying snow with ski pole probing...

Ski penetration ~10 cm, ....Boot penetration all the way ~100+cm
