Observations
Purpose: i went out today to observe the recent avalanche activity from two high elevation rain events in the West-South zone Saturday through Monday.
Terrain: Due to low visibility and high hazard, I kept the tour short and close to Paradise: I traveled out into the Edith Creek Basin, then across well below the Golden Gate bowls and down to 4th Crossing TH, then up the Valley Rd to Paradise.
Weather: Overcast to obscured skies. Very light to light rain. Turning moderate rain as I left the field. Winds increased at 2pm to Moderate gust Strong WNW.
Snowpack: The top 20-25cm of snow was wet with several pooling (very wet layers) below. Pooling layers interspersed with moist layers of small rounded grains. The 12/09 MF crust is still visible 90cm below the surface but breaking down and much softer than in past days.
