Avalanche: Hatcher Pass

Location: Goldmint

Route & General Observations

danteWent for a tour up goldmint to check out snow conditions. Observed widespread collapsing through out the day with settlement of 2-3 inches that spread across an area rarely less than 50 feet and up to 300 feet in wave like motions. Remote triggered one slide on a northerly facing cut bank of the little su while on the flat bench above that released a short wet slab 100 feet wide but entrained enough snow to easily bury someone and entirely fill and dam the stream. The heavy nature of the snow would make staying in control close to impossible if entangled in steeper terrain. Returning to the scene an hour later water had risen behind the debris up to a foot while down stream water lines on rocks were exposed 6 inches. Crowns were visible in all the north facing tributary terrain stretching 100s of yards in width in all elevation bands. Given the constant whoompfing and endless number of visible warning signs, we did not leave the valley bottom. Boot penetration was knee deep.

Avalanche Details

All observed slides apeared to be on the recent storm layer. A quick pit found this layer to be reactive at low compression scores (ECPT 7). Snow consistency was very wet and conducive to rapid deterioration as it moved down slope. All the previous slides we could observe showed a loose wet nature. Our damalanche slide also pulled out some older deeper slab and exposed some dirt.

Red Flags
Red flags are simple visual clues that are a sign of potential avalanche danger. Please record any sign of red flags below.
Obvious signs of instability
Recent Avalanches?Yes
Collapsing (Whumphing)?Yes
Cracking (Shooting cracks)?Yes
Observer Comments

Whoompfing all day long. Ample evidence of still active slide activity on adjacent slopes. woompfing became both more active and encompassing greater amounts of terrain was we moved into colder more shaded parts of the valley.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Nice for early May? Very warm, sunny, no to light breeze.

Snow surface

A light dusting of snow on a one inch wet crust over a little over a foot of heavy wet unconsolidated snow.


Below the heavy wet uncondolidated snow, the snow changed density (stiffer, more slab like, but inconsistent).
