WHERE TO SKI? We have discount lift tickets for Snowbird, Powder Mountain, Park City, Sundance, Alta, Brian Head and Wolf Mountain. Tickets were donated by the ski resorts to help UAC funding. Click on the Online Store below for details.
We were interested to see why SE-facing aspects may be included among the deep slab instability danger rose, so we decided to dig a pit on one to see what we could find.
We found a snowpack with little energy, but with an interesting structure. Multiple suncrusts were no surprise, but what was not immediately apparent to us was a stout ice lens just below a suncrust at midpack. The two crusts sandwiched a <1-cm deep layer of 0.5 mm facets. Propagation did occur at this interface on ECT28, and I'm wondering if the slab would've popped with more energy if we'd been on a steeper aspect.
Basal facets are healing and weren't reactive in tests.
