Weather Comments
Generally a greybird day, with mostly broken skies and occasional glimpses of sunshine. Winds stayed light where we traveled, though we noticed some moderate gusts on the drive home. Upper elevation terrain showed significant past wind loading, with textured surfaces, large cornices, and scoured windward slopes.

Snow Characteristics Comments
Soft, dry snow lingers on upper elevation shaded slopes from east to northwest, while lower elevations and sunnier aspects saw damp surfaces, many of which have crusted over. In the lower elevations outside Wasatch State Park, solar slopes were already down to dirt and grass.
Higher up in the wind zone, the terrain showed clear signs of heavy wind impact. Textured surfaces were widespread, cornices were large—some already having broken off—and windward slopes in places had been stripped down to the ground.

Poor Snowpack Structure
Comments
Traveled around the Ant Knolls area to get a better sense of how much new snow fell, overall snow depth, wind patterns, and the state of the repeater slopes. We took multiple Smart Probe readings across different aspects.
Overall, the snowpack structure looked similar to the central Wasatch. This area received less snowfall during the last storm, but snow depth is generally between 2–3 meters in most places that haven’t previously avalanched, melted out, or been stripped by the wind.
The primary concern remains the repeater slopes, like Ant Hill, which still hold a generally shallow and weak snowpack with facets near the base. While we saw poor snowpack structure, there was no sign of another recent slide. Given all the snow since March—and with plenty of tracks in there—those were solid testers on the weak snowpack. But it’s still a good reminder that weak layers persist, especially outside the core. These are the zones I’d be most concerned about waking up with additional load, warm temperatures, or heavy rainfall, as it wouldn’t take much for the shallow snowpack to become fully saturated and fail on the faceted grains.
Outside the repeater slopes, the main concerns are large cornices breaking off and some isolated wind slabs. The wind has already done most of its work, and we didn’t see much evidence of activity within the wind-drifted snow. That said, given the clear signs of transport, it’s likely that one could still find a wind slab on upper elevation, colder aspects.
