Snowpit Observations
More detailed information about the snowpack: 

Today we skied off the backside of Mammoth Mountain into Turkey Bowl and Fresno Bowl.  By 11 the snow had softened enough to be pleasant skiing on a SE Aspect in turkey bowl.  We took obs at the top of this run and the bottom.  Temp at 11 AM was 4 degrees C and the boot pen here was 15cm where we punched through the crust.  A little lower elevation at 11:30 it was 6 degrees C.  Boot pen here was 3cm where we didn't break through the crust.  We found the snowpack in these SE and S locations to be between 120 and 130 cm.

In Fresno Bowl Height of snow was 90 cm on a S aspect at ~9500 feet.  Clouds had increased from few to Broken Sky with a lot of it being thin and high cloud.  Boot pen here was 5cm where we didn't break through the crust.  Air temp was 4.5 degrees C.  Here we dug a hasty pit to observe the thickness of the crust and found percolation columns down about 12cm.  These columns were about 3-4cm long.  See photo.  Has anyone else found these?  T20 here was -0.5 degrees C.

The most interesting part of the touring today was the variety of surface textures we traversed from softening psuedo-corn to sastrugi to boiler plate wind slab to lacy crust that crinkled under our boards.
