Avalanche:
Location: Bomber Pass area
Ski loop over Bomber Pass and Snowbird Pass. Two avalanche signs: one recent fracture line above Upper Reed Lake, and recent debris from smaller avalanche(s) on a west-facing slope above the Snowbird Mine (Glacier Creek, flowing into Reed Creek). No other avalanches seen, but light was very flat.
Avalanche Details
Fracture line 150 feet below the SW ridge of Lynx Peak (6536), on a convex slope between gullies. Crown depth 1-3 feet? Ground or boulders visible at points in the starting zone. Avalanche was on steeper slope. Fell over cliff at bottom of starting zone.
Obvious signs of instability
| Recent Avalanches? | Yes |
| Collapsing (Whumphing)? | No |
| Cracking (Shooting cracks)? | No |
Observer Comments
One natural avalanche on NW-facing slope. Big cornicing on Lynx Peak ridgelines.
Weather
Light north wind. Temperature in teens or low 20's.
Snow surface
Windblown snow surface from wind earlier in the week. Crusty.
Snowpack
Pit in basin above Upper Reed Lake below Bomber Pass. 1"-3" powdery snow on top of a hard wind crust, then 3-4" faceted snow transitioning to a deep layer of harder snow. Old ice crust about 2 feet down, but not weak.
Variable snowpack on the steeper aspects near the top of the climb to Bomber Pass from Reed Lake (south-south-west slope). Windblown surface. 1-4" wind slab in places, but not extensive. Icy crust on the surface in other places. Deep soft faceted snow on top of harder snow in many areas, especially around rocks. In shallow snowpack (4-20" ice-axe depth), all of the snow under the crust was faceted to the ground. Boots occasionally plunged through the crust to depth of up to 10", other times it was necessary to kick harder into the crust to make steps and use force to plunge the ice axe into the snow.
