Snowpit Observations
More detailed information about the snowpack: 

Today we toured into the Lakes Basin in the Lake Mary area.

We found variable thickness of the storm snow(HST) from 0cm where scoured to 30cm where deposited by wind.  The average new snow depth appeared to by 15 cm or 6 inches.  We saw only isolated stiffening of the wind deposited snow into wind slab near the edges of the lakes and in other areas along the road.  When we moved into the trees we saw even more limited signs of slab formation with only isolated cracking around our skis during informal slope testing. 

Ski quality was great and it was nice to go into the white room a few times today.  We definitely avoided the mid and uper elevation terrain where we would almost certainly have found sensitive wind slab and possible variable ski conditions.

Nice to see enough snow to make one of these!

Things are getting real out there.  Support ESAC to get the forecast you need to go touring.

It's skiing great out there.  The trick is to keep out of harms way.  ESAC can help.
