We toured off Point Six from Snowbowl down the south and west aspects of Jenny Bowl and north-facing Burgandy Bowl. North and west aspects host wind-packed and scoured snow surfaces in open terrain and ridgelines. Protected areas have up to 6 inches (20 cm) of low-density snow over icy crusts. The rain crust disappears above approximately 7,700 feet in this zone. We found up to 30 inches (75 cm) of snow above the crusts in the protected south-facing wind-loaded trees of Jenny Bowl at 7,600 feet. We observed some cracking in the top 6 inches on test drifts on east slopes that were stubborn to release. Large cornices linger on east-facing ridgelines. Our primary concern is avalanches running on the rain crust as temperatures warm up and we receive more snow.
