More detailed information about the snowpack: 

Ryan and I rode up Hwy 108 yesterday and found some interesting conditions.  The road had been recently packed down by the MCMWTC snowcats up to Sardine Meadows but had 1.5' of new snow on top with localized deeper pockets in wind drifted areas.  This made riding up there doable and pretty enjoyable.  Once past Sardine there was 3-3.5' of new snow on top of the road and we sunk in pretty fast and had to dig out and turn the sleds around.  Winds were blowing hard up high with visible snow transport, even scouring ridge lines (pic 1).  We saw a few dry loose natural avalanches but didn't see any other activity from where we were.  We dug a pit just above lower Leavitt Lake Rd on a 30 degree SE facing slope.  We found 80 cm of new snow sitting on top of a thick rain crust from this past Wednesday.  Stability tests showed some instability within the new snow due to density changes an a propogation in an ECT on the rain crust (ECTP24).  Avalanche conditions will be very dangerous through Monday with very heavy snow and gale force SW winds.  I expect numerous large natural avalanches during this time.  It is advised to remain away from any avalanche path over the next couple of days.  It also may be very difficult to get up the road if it has not been previously packed down.
