More detailed information about the snowpack: 

The intense temperatures of February 1st really established a robust melt/freeze crust throughout the Negatives and San Joaquin Mountain area on virtually all aspects except due North at and above tree line. Temperatures remained quite cold today and nothing softened up even at low elevations and in direct sun. The northerly alpine terrain is heavily wind effected and is about as firm as it gets. Southerly aspects up to 11000ft had a hard glaze all the way to the top. A few thin cross loaded strips in the leeward of the last windswept whitebark pine at extreme tree line held the only semblance of micro wind slab that I could find. Very sheltered SE aspects had a skiff of new snow residing on melt/freeze surfaces and deep sheltered northerly trees and protected northerly slopes still had forgiving surfaces. The entirety of the rest of the terrain either has grippy melt/freeze crusts or is composed of alpine sastrugi or boiler plate. Great contouring to be had today on smooth, firm surfaces and cruising through and around features on lower angle terrain was a breeze. One look at the condition of the Negatives, and I went back down the hourglass and out by the upper glass creek meadows. The frigid temperatures of the past two days following the big melt down have really locked and sealed things up. Plenty of needle cast and trees that got wrecked by our most recent wind event. Hopefully the next significant storm that rolls in will be warm and wet to bond to all the super firm surfaces and established crusts. Will see if this February 1st heat up event plays any roll in future avalanche conditions.
