Bacon Rind Surface Hoar

Bacon Rind Surface Hoar

Surface hoar buried 18" deep is fracturing clean.  As we skinned uphill we got collapsing and cracking on this layer. Our Extended Column Test propagated with 5 taps (see video).  Isolating a column for a compression Test the surface hoar broke before I even tapped it (CTV, Q1).  This slope was 20 degrees steep and east facing in the southern Madison Range.  Photo by GNFAC
