Yet another avalanche cycle…

A look into Tuckerman Ravine following the 8″ snow which fell on calm winds on Feb 15/16.  Slowly increasing NW winds into the 50-60 mph range Thursday afternoon ramped up higher through the night. Here’s a look at the avalanches that resulted and the terrain as of Friday at around 1pm. 68″ of snow has fallen in February with 94″ on the ground at the snow plot near Hermit Lake.

 

Note the crown line low on the slope below Chute. Ice crust was evident in several areas in or near debris.

 

Lobster Claw and other south facing lines are top to bottom.

 

Right Gully has really filled in and Sluice appears to have released a pretty good sized avalanche into Lunch Rocks if not in yesterdays storm then during the last storm.

 

It appears that most of Chute through Center Bowl and Lip avalanched once around the same time and then reloaded. Another crown was visible near the Tuckerman Trail traverse through the Lip as well.

 

Lunch Rocks is still visible but just barely. The upper crown line in the Lip is heavily eroded which indicates it failed early on. It’s just visible in the upper right.
