Test results:
ECTNR: Did not see fracture and propagation although I expected to see both. At HS 122 I had difficulty effectively isolating the column by myself
First CTM #15
Second CTM #12 (see video) Failing on the persistent weak layer.
One take away: an avalanche stepping down to the PWL at 6659' N would be 2.5 to 3 ft deep.
