Wolverine Ridge, Purple Mound & Lipalian

Skied along Wolverine Ridge to Purple Mound and Lipalian Mountain before descending to Larch Chair. Experienced a whumpf while traversing Wolverine Ridge, followed by the observation of a shooting crack(s) on the slope below. Two members of the party experienced a whumpf traversing near the summit of Purple Mound, and another whumpf on the flat ridge before Purple Mound. We opted to stay on the ridge, and ski a conservative descent line.
