Kernpunkte

Clear skies, intense sun, and freezing levels 1600m+ for Sunday. despite the melt-freeze cycle, do not underestimate solar radiation destabilizing the snowpack. Cornices are huge and with sun, expect some to fall acting as large triggers above you.

    Slabs are present on exposed slopes and steep gully sidewalls. A few significant natural wind slab releases were noted Friday one being fairly wide, 38degrees and 50cm deep off Mt Kitcheners ridge facing the Icefields center. Keep this on your radar.

    When the sun comes out expect a higher probability of naturally occurring moist avalanches especially in and around steep gullies, rocks, and alpine bowls. Recent activity of this nature have initiated deeper instabilities ie. windslabs / deep slabs.

    These deeper layers can wake up unexpectedly. A size 3 was triggered last Sunday at the Icefields from a shallow spot. Investigate for this weakness before committing. Profile today found the Feb14 surface hoar buried 80cm, unreactive yet present.
