The 2 to 4 inches of snow that fell on Tuesday was very dense and appeared to have fallen as damp grains and served as a great spongy base. Then the PI ramped up around 1700 on Tuesday evening, and continued with S2 rates until 2000 and dropped another 5 to 8 inches of medium density snow, with another brief shot in the early morning hours. HST ranged from 5 to 10 inches depending on location and elevation with the upper BCC zone in the Catherine Basin area getting the Lion's Share. The riding was good in dense spring powder and even some of the snow that got damp rode well in the upper elevations. Lower elevations were getting sticky on the low angle by 1100.
The previously cited winds were creating upslope and cross loaded soft/shallow wind slabs. Minimal cracking in these wind slabs were observed; and by the end of the morning hours variable riding conditions were being created. North and NW facing slopes in the upper alpine were getting striped in many locations. and all aspects were getting damp besides due N wit angles 30 degrees and greater.
See above for the previously cited problem interface, and with the warm tempertures on Wednesday, this problem interface may have yielded more activity in the afternoon hours. The winds appeared to be serving as a contributing factor enhancing this storm slab issue in many locations in the exposed upper alpine. All that said, once the temperatures cool off later in the day and through the evening these problem issues most likely will decrease and or vanish by Thursday.
Widespread wet loose activity and roller balls observed from 0900 on. Of note, a group of skiers riding the steep easterly facing terrain in the Rocky Points area were easily triggering small wet loose slides. As the sun moved around the compass this issue obviously appeared to travel with it into the afternoon hours.
See picture below, and in particular the right flank of this small wet loose. This slide tried to propagate into a wet slab, but the slope angle let up. This slide occurred at 1045 and was on an easterly aspect at 9800 feet and was initiated by roller balls coming off the rocks above it.
