Problem #1 Comments

Still poor structure in many places. High shady aspects are still guilty in my book around this area. No propagation in ECT's but upon prying with moderate pressure after the test a clean shear was produced 42cm down on 1-2mm squares. Just need to find the slab and weak spot.

Problem #2 Comments

Some stubborn wind drifts in cross laded terrain above 95000' with minor cracking noticed. Possibility of a wind slab stepping down into a deeper weak layer in locations.
