Buried surface hoar easily propagated in ECT.
Bottom Line
We set out to look for buried surface hoar and found two distinct layers on a northeast aspect near the top of Mount Fuji. It showed easy and sudden propagation in extended column tests. The exact extent to which it lingers needs further investigation. We did not find it in the few holes we dug below 5,800 feet. We chose to travel one at a time and avoid steep slopes with rollovers or associated terrain traps.
