Highlights

The avalanche danger is MODERATE, and wet avalanches are possible. Frozen snow surfaces this morning will quickly soften as daytime heat weakens the snowpack. Heightened avalanche conditions exist on mid and upper-elevation slopes where the snow will become saturated. Avoid traveling on or underneath slopes steeper than 30 degrees as temperatures rise.

    Last night, temperatures dipped below freezing for the first time in nearly two weeks. However, the cold front was short-lived, and any surfaces that refroze overnight will quickly warm this afternoon. As the snow surface heats up, watch for active roller balls that indicate the snow is losing strength. Large, dangerous wet slab avalanches are possible and may run long distances.

    • If you're sinking into the snow above your ankles, or you're seeing active roller balls, move to shadier slopes or lower-angle terrain.
    • Pay attention to and avoid terrain traps below you, such as gullies or cliffs, where even a small avalanche can have severe consequences.
    • As temperatures climb throughout the day, avoid being on or under steep slopes.

Recent Activity

Numerous wet avalanches have been reported across the Logan zone over the past week. These avalanches have been large enough to carry a person into consequential terrain or even bury them.

Recent natural wet avalanches are visible from the valley in the Box Elder Cirque in the Wellsville Mountain Wilderness.

Snow and Weather

Overnight, mountain temperatures finally dipped below freezing. This morning, weather stations across the Logan zone range from the low 20s°F to just below 32°F. Snow surfaces will be frozen this morning, but will quickly soften as temperatures rise throughout the day. Yesterday, we traveled in the Copenhagen Basin area and found very poor riding conditions. In one meadow, our sleds broke through the surface slush into 3-4 feet of ice-cold water. While conditions will be slightly improved today, snow surfaces will likely return to a saturated mess by this afternoon. On days like today, it's a good idea to weigh the risks versus the rewards of travel and riding conditions.

This morning at 0500, the UAC Card Canyon weather station at 8700 feet reports 29°F and 39 inches of total snow. It's 31°F at the Tony Grove Snotel, with 47 inches of total snow. On Logan Peak, winds are blowing 5-10 mph from the north. It's 26°F on Paris Peak at 9500 feet, and the winds are blowing 8-10 mph from the east. Today, expect mostly sunny skies and temperatures reaching the low 50s°F. Warm, light winds from the north and east will do little to keep surfaces cool in the heat of the day. This weekend, record-breaking warmth returns to the region before a shift in the weather arrives next Tuesday.

Report from our travels in Copenhagen Basin yesterday.

Additional Info

  • Travel with a partner, and cross or ride slopes steeper than 30 degrees one at a time while the rest of your group watches from a safe spot.
  • Ensure that everyone in the group has avalanche rescue equipment (a transceiver, probe, and shovel) and knows how to use it.
