Problem #1 Comments
Dug a pit at ~8600ft NE facing on Memorial 3. Had ECTP26 60cm down on 1mm facets. HS180, dug pit to 105cm down. Facets were showing signs of rounding but pretty bouncy with very little sintering under a loupe. PWL thickness was 9cm.
Comments
Dug another pit at 8000ft NE facing, lower down in Memorial 3. Found a 25cm layer of graupel under a thin, soft, temperature crust, about 3cm thick. This layer disappeared in the 8600ft pit. The PWL was 40cm down, but was unreactive in tests, well rounded, and sintered.
