Snowpit Observations
More detailed information about the snowpack: 

On January 20th to 22nd we headed down to the Mount Whitney zone to do a winter ascent of the Mountaineers Route.  It was interesting to head south in the range to see the difference in overall snow coverage.  The verdict, its even thinner the further south you get.  For those of you lamenting thin coverage in the Mammoth area, you should feel good about what you've got.  The only skiable snow we found was in the Mountaineers Gully at around 13,000 feet for about 20 turns.  The other thing to note was the variability of snow depth from 0 cm to 45 or 50 cm on sheltered north facing terrain.  On south slopes the coverage was 0 cm from the valley floor to the summits of the 14ers.  It truly felt like October down there instead of late January.

To be clear we did not ski.  Snowpack analysis and avalanche hazard is not just for the backcountry skier or snowboarder.  You could argue that it is even more critical for alpine climbers to be aware of the snowpack since it would take a relatively very small avalanche to be consequential to a climber who may be in exposed terrain often.

When we traversed the pockets of wind drifted or sheltered snow, in gully features we found localized cracking around our boots from wind stiffened snow.  We did not find these to be consequential in size.  Finding one large enough to be consequential would be difficult right now without additional loading.  The low snowpack eased our foot travel even though it was a bit depressing to look at it as a backcountry skier.  For now I'll be focusing my touring in the northern part of the range.

More detailed information about the weather: 

During our time in the mountains we witnessed a dramatic shift in the weather.  Springlike conditions gave way to gusty and stormy conditions by the time we left the portal.

On 1/20 and 1/21 we had clear skies to few clouds with calm conditions.  Daytime temperatures stayed well below freezing, especially in the shade.  Night time temperatures crept down to near 0 degrees F.

On the night of 1/21 though 1/22 the winds increased from calm to Strong winds from the NE.  Intermittent clouds and flurries of snow fell overnight and as we descended back to the valley.  It was clear we did not want to be moving up the mountain given the change in weather.
