Edith's Knob above the Valley Rd. Three natural loose wet avalanches occurred around noon and crossed a section of the summer Skyline Trail. All three were relatively small but could knock you off your feet.
Signs of Unstable Snow
Snowpack: Height of snow: 6' (180cm), Recent snow 12-18" (30-45cm) over a very thin rain crust (11/24). A more pronounced and firm crust (11/17) was found down 2-2.5' (60-80cm).
Most active layer in snopwack test was a mid storm layer down 10-15" (25-40cm) on large (2mm) preserved stellar (see photo of tilt test). This failure was always about 1" (2-3cm) above the 11/24 rain crust.
Weather: Few clouds. Moderate to strong ridgeline winds. Warm temperatures above freezing.
