Avalanches: Intentionally triggered several road banks and small steeper rolls. All D1-1.5. Persistent slab problem was very reactive today. Poor vis limited obs in other areas.
Weather: Warmest in the morning with cold temps in the afternoon. Light snow and light winds throughout the day with maybe an additional inch or two of accumulation.
Snowpack: It’s broke. Multiple large booming collapses. Many shooting cracks. Surprisingly some steeper slopes around 35* cracked but did not slide. Snowpack was less reactive in areas that slide last week.
