Instability Hyalite Drainage

Skied two low angle meadow laps. Continued up towards Hyalite. Consistent whumphing when breaking trail. We dug a pit a bit before the first steep rollover on the way to Hyalite Peak (~9200’). ECTP18, broke 50cm deep where the storm slap interfaced with facets. Total depth 130cm. Consistent beefy storm slab underneath 4-5” of fresh snow once out of the thick trees. Snow so unsupportive we couldn’t walk 15 feet to dig our pit. 

we also observed signs of recent natural avalanche activity in Divide Basin
