Snowpit Observations
More detailed information about the snowpack: 

Started at road closure on South Lake Road (8800 ft). 

0930 - about 2 cm new snow at parking lot.  Strong SW wind with visible snow transport over all nearby ridges. Air temp=5C. Sunny with few thin, high clouds.

Toured south along road, about 1 mile south from road closure then up E and SE facing slopes on Table Mountain. These were mostly wind scoured, to the point that old ski tracks appeared raised above melt/freeze crust.

1030- South aspects at 9200-9600 feet beginning to melt

1100- Continued up E-NE facing slopes in low angle, sheltered trees.  Wind deposited snow here, ski penetration ankle deep. Dug numerous hand pits on these slopes.  No failures noted.  No cracking or whumping.

1200- Stopped at 10,800 ft below ridge line.  Strong gusty winds.  At this point wind slabs were noted on low angle slopes.  Hand pits failing on isolation, between 10-20cm depth. Air temp= -3C. Cornices forming on E-NE aspects of ridge top.

Below ridge, skiing was surprisingly good in wind deposited aspects.  Firm melt/freeze crust on other aspects.

1215- Significantly less snow transport noted over ridge tops. Air temp at 8800ft= 4C.
