Easy SP and SC tests.
Observation: Summit
Location: Manitoba, Tenderfoot, Colorado
Spent Fri, Sat, and Sun poking around Summit. We confirmed the buried surface hoar exists between 2-3500′ on multiple aspects, 30-40cm down, with variable test results. The most reactive were easy ECTP near treeline where the BSH was intact 3-4mm. At treeline and above we found old facets 2-3mm buried about the same depth ~30-40cm deep reactive in most tests with easy to moderate sudden collapse.
