DEEP SNOW SAFETY

“The ultimate safety device, the human brain, can be as deadly as it can be protective.” C. Van Tilburg

This web page is presented by the Alpental Volunteer Ski Patrol as an educational public service communication.

Tree-well and open-slope deep snow submersions are generally under reported events. Tree-well submersion is a hazard well known to snowshoers and backcountry skiers and boarders, but is also a documented occurrence within ski area boundaries. These hazards are confined largely to Western North America ski terrain characterized by coniferous trees and deep snow.

In this region, we have experienced reports of non-fatal deep snow submersions every year. This usually happens in the early part of the season when the snow pack is unconsolidated and likely to leave relative voids around the base of trees, as well as near large rocks and stream beds. It should be noted that snowboarders may have more difficulty removing their equipment when inverted, but these hazards pose an equal risk to skiers and snowboarders. All winter sport recreationalists are at risk for "non-avalanche related snow immersion death" (NARSID) events and should maintain awareness of this hazard during and immediately after large snow falls.

Huh...I lost you at tree-well?  Let's back up then...

How can I prevent these events?

• Recognize gladed terrain and avoid tree wells
  
• If falling towards a tree, try to grab a branch to avoid falling head first into the well.
  
• ABSOLUTELY  DO NOT ski or board alone in fresh deep snow!
  
• Maintain visual or verbal contact with your partner at all times.
  
• Carry and know how to use an avalanche tranceiver.
  
• Ski and board within your abilities.
  
• Maintain particular vigilance on powder days.
