General Comments

A natural avalanche cycle occurred on Timpanogos during the storm on March 7th.  This was a deep slab release that I observed.  It was the only deep slab that I saw but Nalli stated he observed more to the east side of Timpanogos.  I did not climb to look at the crown but in areas I did travel I found a layer of weak faceted snow above the January rain crust.  It's most likely that this deep slab had a weak layer above or below the January rain crust.  The location of this avalanche is indicated on the map below.

General Comments 2

There was also a widespread natural cycle within the new snow which was about a foot deep.  These were mostly class 2's but some of the piles of debris I wouldn't have wanted to tangle with.  The new snow had stabilized by the time we were there.
