Snowpit Observations
More detailed information about the snowpack: 

Toured in the June backcountry today to look at how the recent snow is stablizing. During the tour we experienced no cracking, whumpfing or recent avalanche activity.  5-8cm of snow fell overnight at the 10,000 ft level.  Cold overnight temps pulled out alot of moisture from the recent snows, making for 20-25cm of soft snow in the most sheltered areas.  Ski pen = 25-30 cm.  Boot pen = knee deep. Air temp at 11,000 ft an noon was -9C. 

We toured up the Hourglass under clear skies, cold air temps and a moderate East/Northeast wind. Some snow was being transported along the surface and over ridges, though the wind decreased during the day. Above treeline, snow showed texturing from the wind but not was not heavily wind affected.

Digging hand pits in the Hourglass and other N/NE areas today, I had several planar failures with moderate to strong force.  Below the fist hard surface snow is a 1 finger dense layer, 10-12 cm thick. Most hand pits failed at the bottom of this layer.  Stomping on convexities during the tour produced cracking under foot but nothing that propagated.  Above treeline we saw several small-medium sized cornices (see photo) overhanging east facing slopes. 

Despite cold air temps, some melting was occuring on all but N-NE slopes today. Enough melting that E, S and W will have a crust on them tomorrow. We noticed a few small point releases from today and many that looked to be from yesterday.
