When cold, dry snow becomes wet for the first time, it almost always means wet sluffs (loose snow that fans outward as it descends).

Larger wet slab avalanches can happen when melt water percolates through a layered, winter snowpack for the first time especially after 3 days of strong melting combined with no refreeze at night.

Luckily, wet avalanches usually don't last forever because over time, days or weeks of percolating meltwater, all the layers in the snow disappear, and the snow becomes homogenous and dense, turning into a stable summer-like snowpack. Typically, this cycle of instability maturing into stability occurs first on the south-facing slopes in early spring, then progresses to the east and west-facing slopes in mid-spring, and finally, by late spring, the upper elevation north facing slopes go through a wet avalanche cycle.

Finally, glide avalanches occur regularly in spring as the entire snowpack slides slowly on the ground like a glacier until they suddenly release into a full-depth avalanche. These occur periodically on steep rock slabs and occasionally on steep grassy slopes. Notorious glide avalanche locations include Stairs Gulch or the rock slabs in Broads Fork, which you should always avoid in spring. Avoid crossing under any slopes with telltale glide cracks in the snowpack. Remember, they come down randomly, even at night.

We almost always get winter-like snow storms well in the Spring. Treat each storm just like you would in winter. Avalanches can occur within the new snow typically from 1) low-density layers deposited during the storm, 2) high precipitation intensity during a storm, and 3) from wind slabs created during the storm.

It's easy to test the new snow as you travel by jumping on small test slopes to see if they avalanche or dig down with your hand to see how well the new snow is bonding. Snow can change dramatically in both space and time, so never let your guard down. Especially avoid any steep slope with recent wind deposits, which are almost always dangerous.

Practice the usual backcountry protocol, go one at a time, never travel above other people and practice all the usual risk reduction measures and low-risk travel rituals you learn in avalanche classes.

Each storm will be worth looking at the winds to find out which direction they have blown from and what direction they will be blowing for the day. Wind can rapidly load snow onto steep slopes, making those slopes more prone to avalanching. The wind drifted snow looks rounded and pillowy; in some cases, it can sound hollow like a drum. If you see shooting cracks, it's a sign you may have hit a wind slab. Check upper elevation winds for speed and direction on Logan Peak or Paris Peak.
