Our January 9th persistent weak layer appears to be healing, but we were able to get fracture initiation and propagation on NW and S aspects. It is still worth investigating and performing and extended column test before committing to slopes with consequential features like cliff bands and steep gullies.
Winds were not as strong as forecasted, and temperatures did not get above freezing as predicted. Precipitation varied from none to moderate.
CT 24 SP down 65 cm on 3-4mm rounding facets
ECTP 22 on same layer on south aspect at 5740 elevation
ECTN 22 on same layer on northwest aspect
RB 5 on same layer on northwest aspect
Persistent weak layer from January 9th ranging between 55 to 65 cm (26") in depth.
Our mindset was status quo due to the uncertainty regarding the sensitivity of the weak layer. We stuck to 30 degree slope angles in light of this.Close
