Zone or Region:
Washington Pass - north of WaPass Overlook, on SE ridge of Hink House
Did you observe any avalanches? Yes
Size 2: Could bury, injure, or kill a person
Didn't see the trigger, began in the rock chutes north of Wa Pass overlook Some debris ran to highway, approx 1800 feet from where we first observed the avalanche to terminus, west side of highway. There was no flow across the highway, but some chunks of snow and ice, up to 2ft in diameter did make it to the highway. No impediment to sled travel.
Weather was sunny in the morning with scattered clouds, cloud layer sitting around 7K down valley, but considerably higher at pass. By 11:30, sky changed to overcast, light precip started over WA Pass, falling as very light and intermittent snow. Winds light to moderate, S / SE. Avalanche observed at 2:00pm, from the hairpin.
