Low hazard does not mean no hazard.
Spring sun and daily temperature fluctuations will weaken cornices. Use caution and limit exposure to these large triggers.
Pay attention to your sluff in steep terrain. There is enough dry, loose powder on the surface that can quickly build up and push you off your feet.
No notable natural avalanches have been observed over the last few days in Glacier park. See MIN report for small, human triggered wind slab on Wednesday.
Near neighbours have been reporting cornice failures this week, both natural and explosive triggered.
A widespread, natural avalanche cycle occurred up to size 4.0 on Mar 19-20 during the atmospheric river. Check out pics from this exceptional avalanche cycle in the MIN Reports.
Expect widespread surface sun crusts. Sheltered polar alpine terrain holds dry, loose snow lying on a firm crust. Wind slabs might be lingering in exposed terrain.
Large cornices can found on ridgetops.
A series of crusts formed in March are present down 50-150 cm.
Travel can be challenging below treeline with frozen tree bombs and huge avalanche debris from the mid-March atmospheric river.
Spring weather is forecast with sun, cloud and flurries. Temps will rise into the weekend.
