Weather today was mixed with mostly cloudy skies, temperatures in the single digits, and the winds were light to moderate out of the NW with transport moderate. While ascending the ridge of Rocky Points from Katherine's Pass I triggered three avalanches in the first three chutes. These were triggered by very small cornice drops, walking slope cuts, and gentle stomping on the ridgeline. The snow was very sensitive. Propagation was quick and widespread in this area. The snow that was active was all areas that received loading from the NW winds but had not gotten thick with wind loading. The slabs were all soft slabs and the deepest crown face was 11 inches with the majority of crown faces around 8 inches. In the Second Chute after the slide filtered through a narrow choke it fanned out to 60 feet wide with propagation. All slides were in the new snow only. Widespread cracking was occurring in all starting zones with slopes < 35 degrees not moving more than 5 mm stress cracks. All slides were initiating on slope angles 37 degrees and greater. Slides were not making it to the flats with the deepest debris piles 2 to 3 feet deep. Obviously they most likely wouldn't bury you, but they could ruin your day and push you into a place where you didn't want to go. These slides occurred at 10:00 am. Weak layer was the old snow interface, and there appeared to be light density layer directly above the old snow surface. The aspects ranged from ENE to SE.
On the exit at 3:00 pm I was able to trigger the steep chute on rider's right of the main chute in the Dog Lake Chutes area. This slide was a pocket that was a foot deep and ran to the flat transition. Soft slab again. It started out 20 feet wide and propagated to 60 feet wide as it rolled over the steep section 70 feet down hill. The aspect was NNE. After triggering this Chute I traversed to the Main Chute. In the main Chute I triggered a sluff that was 20 feet wide and taking almost all the new snow. This also ran to the transition. All weak layers were the same as in the Rocky Points area. The slope angles were at least 37 degrees.
After riding on the Dog Leg Chute in the Rocky Points area I went to Point Supreme and skied the North aspect and as well as the South aspect. At this point in time the Supreme area has not opened for the season yet. In steep areas with wind loading (and firm/hard slab loading) I was not experiencing anything more than limited cracking without any movement. The best riding was on the lower half of the Helicopter Shot on Point Supreme. All of the slopes besides the Dog Leg Chute in the Katherine's area were wind damaged with either cross wind destruction or up slope wind waves. Sunset was destroyed.
New snow in Brighton was 8 inches. New snow in the Katherines area and on Point Supreme was closer to 10 inches.
The hazard appeared to be Moderate in areas of wind loading. The hazard on Tuesday may be Considerable with increasing temperatures and solar triggering.
