Eagle River Snow Observations

A relatively small fraction of terrain often frequented by backcountry travelers has a professional daily avalanche forecast available. For this reason, the Alaska Avalanche Information Center encourages users to share what they see.

Please contribute your avalanche, snow and weather observations in the comments below. It could help save lives!

  1. South Fork Eagle River trailhead witness two avalanches morning 3/7 between 10 am and 1:49 in gullies above trail. One skier triggered avalanche but escaped.

    1500-2600′, NE aspect, 1″/hr. We probed drifts to 2m in gullies over the 111204 raincrust. Pockets of windslab to 50cm deep failed on skicut/jump at stormsnow/raincrust interface. Rain line below 1000′.

    Strong southerly wind channeled through S.Fork has stripped slopes and crossloaded most gully features, a sad state of alternating bare ridges and loaded gullies.
    A few avalanches, one to Size 3, are presumed to have run last Saturday or Sunday during the rain/warming event. Some look to have begun as drier slabs that then entrained moist and wet snow lower down, below about 2700′. One avalanche on a SW aspect ran down the gully to within a few meters of Highland Road.
    Height of snow (HS) varied from 0 to 200cm in loaded gullies. Average HS was 45cm. 10cm light dry snow sat atop a breakable meltfreeze crust in protected areas. In exposed areas the crust was bare and quite slick. A mangey mix of decomposing fragments and facets exists below the crust.

    Skied North Bowl, considering how hard the wind was blowing on the ridges, the turns were surprisingly yummy, even a couple faceshots.
    Strong SE wind forming hard windslab in exposed places and building cornices at the top.
    The windslab cracked and easily sheared underneath, but I didn’t see enough uniformity in slab for it to be an issue -yet. The deepest HS I probed was 150cm, quite variable – right down to bare ridges and high features.
    On a protected roll lower down in North Bowl ~3000′, NE aspect, 20 degree slope, I found 120cm HS. 30cm Fist HST over 20cm of 1Finger windslab over decomposing old storm snow bonded to an old MF layer on top of 20cm of facets at the ground. I didn’t have any significant shears. Although I suspect the basal facets might be an issue after we get more of a load?
    This snowpack pretty much mirrored what I saw in Hatcher’s yesterday except for more wind effect and deeper snowpack (in protected spots) today in Eagle River.

  5. Great Job providing free avalanche bulletins and snow observation pages all season. Thank you for your tremendous efforts is keeping the backcountry travellers of this great state safe.

  6. Dec. 16 observations from Harp Mountain, South Fork Eagle River:
    52cm HS. No significant shears. Dec. 9 storm snow seems bonded to Thanksgiving crust. Evidence of previous Easterly wind near ridgetops- bare windward features and loaded gullies and pockets. Two avalanches >2 days old observed in steep sideloaded gullies.
