Snowpit Observations
More detailed information about the snowpack: 

We took a series of weather obs and mone snowpack observation today in Visalia Bowl.  On the surface there was a 4 cm MFcr and then moist grains underneath.  See profile graph from field book.

The crust was supportable in many places, except where trees were nearby and boot pen more than doubled.  In the homogenious open areas the boot pen was 15cm and did not break through the base of the MFcr below the Moist Grains.  This was at 9900 feet on a SE aspect and 24 degree incline.

Steeper slopes certainly had more melting going on and skied better.  We did trigger a couple very small loose wet sloughs today on a very steep rollover.  See video.  Not a huge surprise, but of note if you were going to go to a consistently steep and confined terrain feature.

Avalanches don't discriminate between big snow years and low snow years.  At some point you are going to need a forecast!

Definitely a cooler day than yesterday out there, but still warming that was enough to softent the surface.  Northerly winds with some transport, but not significant to make a slab.  See photo.
