April 23rd was the 150th and final avalanche advisory of the 2016-2017 season. Click here for more information regarding this scheduled end date.
Unstable wet snow/signs of loose wet avalanche problems observed on the E aspect of Rubicon Peak just above 9,000' late this morning. Roller ball activity was easy to initiate (video). A ski cut placed on a test slope in the area of easy to initiate roller ball activity produced a 3 inch deep loose wet avalanche (photo).
N aspects held mosty breakable crust conditions at mid day. In some of the sun exposed lower angle N aspect areas, the surface crust had melted away to leave about 1 inch of wet snow on the surface. Recent storm snow unaffected by melt-freeze existed below either the breakable crust on melted crust/surface wet snow. Transitional snow surface conditions.
Ski cut placed on test slope just after roller ball video was taken produced this shallow loose wet avalanche.
Increasing cloud cover during the morning hours. Nearly full sun for much of the morning gave way to fairly thick high level cloud cover at mid day.
