Snowpit Observations
More detailed information about the snowpack: 

Quick afternoon tour up from the end of Old Mammoth Rd. towards Red Cone to check out snow depths and general conditions. Back down the same way. Moderate to strong N and E winds blowing above about 9500' transporting the new storm snow over the Mammoth Crest and onto S and W aspects (Think the skier's right side of Red Cone Bowl, the sidewalls of the Hollywood Chute, etc.). Video attached. Calm with light gusts at lower elevations.

Snow depths: 40-60cm of snow at Lk. George with the top 15cm being new storm snow. 75-100cm of snow around 9500'-9800' near Crystal Lk., east of the Red Cone with the top 20-30cm new storm snow. In general, the storm snow was cold and dry sitting on top of a 2cm crust that had formed on the old snow surface. In many places, snow below the crust was moist from the past week's warmer temperatures.

If I had to say only 2 things about the current conditions in the area I would say 1. Winds may be loading mid and upper elevation slopes with S and W aspects today. 2. The snowpack is still mostly shallow. Though I haven't seen well any faceted layers yet in my limited travels, it is easier for weak layers to form in a shallow snowpack. Keep an eye out as the temps stay cooler in the next few days. Also, a shallow snowpack means hidden early season obstacles. Watch your skis and your knees out there! Be conservative and think about your season as a whole before you charge it and hurt yourself.
