Preliminary Report 3/10/20

Avalanche Accident 3/9 near Mile 16 road run at Hatcher Pass

A 17yo male, snowboarder triggered an avalanche around 12:30 pm on Monday 3/9. It is believed that the victim strayed off his intended route and subsequently triggered an avalanche on a small slope which funneled into a terrain trap above a creek drainage. Terrain traps compound the risk of any avalanche, no matter the size. The slope was approximately 100’ tall.

The avalanche occurred on a SSW aspect at an elevation of 2000’ and a slope angle of 36 degrees. The avalanche resulted from a storm slab failing on a weak persistent grain faceted layer in the snowpack. The crown of the avalanche is estimated to be 2.5 feet deep.

Prior to the event, Hatcher Pass received a significant amount of snow, approximately 36” in 48 hours. Monday’s report was as follows:
“33″ of snow and 1.7″ of SWE have accumulated at Hatcher Pass since 3/7. The IM snotel at 3550′ is reporting over 100 inches of snow this season! Quite impressive.
This RAPID load will OVERLOAD weak layers and NATURAL AVALANCHES are POSSIBLE today and HUMAN TRIGGERED are LIKELY.
Storm Slabs, Deep Persistent Slabs, and Dry Loose sluffs will be avalanche problems today and into tomorrow. Dangerous avalanche conditions. Careful snowpack evaluation, cautious route-finding, and conservative decision making are essential today.”

This rapid load contributed to a Considerable avalanche danger Saturday through Monday.
We recommend conservative decision making as the snowpack continues to adjust to its new load over the next 24-48 hours.

The avalanche center says that nearly three feet of snow have accumulated at Hatcher Pass since Saturday. This amount of snow is leading to an overload of weak layers with natural avalanche and human triggered avalanches likely, which will lead to avalanche problems through Tuesday. 33″ of snow fell in 2-days.
