Avalanche: Seward

Location: Eastern Kenai Peninsula

Route & General Observations

Flight from Anchorage to Moose Pass area. Landed Madson mountain (5300’). Then bumped south to Lost Lake wx station for assessment/ repair. We were able to get data transfer working again though anemometer still needs repair. So no wind data until Chugach Avy staff returns via snowmachine.

Flew the ARR corridor north from Moose Pass over Grandview, Spencer Lake and Squirrel Flats. Lots of glide cracks/ avalanches region-wide. Some looked to have released recently (during cold snap).
