We dug snowpits at 2000' on a W aspect along the SW ridge of Lipps and at 2100' on the N aspect of Pete's N.
On Lipps we had propagation on a storm interface about 30 cm (12") down from the surface (ECT P 14). It took multiple hits for the fracture to propagate all the way across the block. The 1/10 buried surface hoar was 100 cm (40") down and had no results in this pit.
On Pete's N we had propagation on a weak layer about 15cm (6") deep, that might have been the most recent surface hoar layer from 2/15. We also had propagation on the 1/10 buried surface hoar in one pit (ECT P 15). This pit had a shallow overall snowpack and the 1/10 BSH was only 50 cm (20") deep. In an adjacent pit we did a propagation saw test which propagated to the end with a moderate cut length (35/100 end). Both these results indicate the the 1/10 BSH was reactive in this area and it is possible for a person to trigger from a thin spot.
