Quick report

Cracking
specific

A few baby slabs broke for me on small wind rolls. Otherwise, I got cracking in punchy 10cm thick hard slabs. Specific cracking on unsupported terrain or at the edges where slabs were thinner/softer. Trending less sensitive throughout the day.

Snowpack

  • Last night's wind stiffened almost all surfaces into a punchy, 10 cm thick, hard wind board over softer snow from the last storm.
  • Low-angle, north, very sheltered trees above 9500' showed the least wind effects. Ski penetration there: 25cm. Under the wind-stiffened snow with softer snow underneath, there is a hard wind board/crust from between the most recent storms.
  • Cloud cover and L W wind seemed to have delayed and limited solar warming. No new activity or rollers. No greenhousing, Northerlies stayed dry winter snow to the bottom of the lower gullies mid-afternoon. East, south, and west aspects below about 10,500 ft. got moist and refroze quickly.
  • Pole probing ~10,000 ft. on northerly aspects: Snow depth = 135 cm.
    • The upper snowpack is strong and right side up. I felt a crust buried in early March down 45 cm, and another hard crust over the January depth hoar down 90 cm.
  • Hard sastrugi at ridges and some large cornices hanging over northeast-facing slopes.
  • Small amounts of snow are available for southwest winds to blow around, but most fetches stripped/melted. Isolated windward areas have 35 cm boot penetration in dry soft snow.
