EVALUATE SNOW AND TERRAIN CAREFULLY

    East winds built stiff drifts or hard wind slabs from this week's snow in unusual or unexpected places and in and around terrain features up high. There were several avalanches of wind drifted snow yesterday in the Wasatch Range, and a few people have been caught and carried by avalanches this week.

    • Avoid drifts on the lee side of major ridges and in and around terrain features like sub ridges, gullies, and cliff bands.
    • Like big mouse traps, harder wind slabs have a nasty way of allowing people to get out on them before releasing.

  • Loose Wet

    Wet loose avalanches or sluffs entraining this week's new snow will become likely today in steep terrain due to seasonal warmth and intense sun. Solar warming from the high angled April sun will melt yesterday's surface crusts and cause the fresher snow from the last few days to become moist and sticky, and natural and human triggered wet loose avalanches may become likely on very steep sunny slopes.

    • Wet loose avalanches are generally manageable, but can certainly be a problem because of terrain traps, or of course, if people find themselves below an avalanche.
    • Some wet loose avalanches entraining all the recent snow could create large piles of cement-like debris, especially on long steep slopes.

Recent Activity

No new avalanches were reported or observed recently in the Logan Zone.

People triggered a few slab avalanches of wind drifted snow in the past few days and again yesterday in the Salt Lake and Ogden Area mountains. Visit our backcountry observations page for more info, HERE.

This soft slab avalanche of wind drifted fresh snow was intentionally triggered in Big Cottonwood Canyon in the Wasatch Range in the backcountry above Salt Lake City Thursday, 4-15-2021.

Snow and Weather

This is our last regular avalanche forecast for the season. We are certainly in a drought and there is much less than average snow in the mountains, but nice nice spring snow conditions exist currently in the Logan Zone. Although conditions generally become more predictable in the spring, avalanches are still quite possible in steep terrain, and people should always evaluate the snow and terrain carefully when traveling in the mountains.

Additional Info

General Spring Travel Advise:

As daytime temperatures rise, softening the snow, the danger of wet avalanches will increase, so its a good idea to get in the habit of an early start and to plan on heading down before things get too sloppy.

-Watch for trees or other terrain traps below you if you venture onto steep slopes.

-Roller balls, pin-wheels, and natural wet avalanche activity are red flags indicating potential for people to trigger wet avalanches.

-If you start sinking deeply into wet snow, or if the snow you are traveling on becomes unsupportable due to the heat, it's time to leave.
