More detailed information about the snowpack: 

There was 3-6" of new snow on northerly aspects at 9000-11000 ft on slopes above TJ Lake and upwards to the top of the Mammoth Crest. The new snow had bonded strongly due to its high water content and warm ambient temperatures. It was a nearly uniform pasting and provided for slightly slow but supportive snow. I did not observe any sensitive wind slab, shooting cracks or collapsing. As I reached the higher terrain of TJ Bowl the new snow was well bonded, non-reactive and stayed in place when stomped on and ski cut. Total snow depths averaged 150-160cm at 10650ft. I dug a hasty pit to 75cm below the surface on a N (10deg) aspect on a 38 degree slope. New snow measured 15cm and was F hardness. From 15cm down to 30cm hardness changed to 4F and below hardness went to 1F. Two compression tests both produced CTM11 Q2 results on the hardness change from 4F to 1F at 30cm below the surface.

More detailed information about the weather: 

As I toured through the Mammoth Lakes basin the winds started to calm down around noon, yet it was apparent that they continued at higher elevations for the majority of the early afternoon. The typical Mammoth cloud hung over the crest and enveloped Mammoth Mountain for most of the day. Although it was blustery this morning, air temperatures were warm and the snow was fairly wet and sticky, even with waxed skins. Below the crest on the leeward side winds were fairly light and swirling from different directions, and snow transport was minimal.
