Quick report

Diving up from Gorham, I noted how visible the slide path on the NE aspect of Mount Madison was. I understand this ran big in the winter of 1968-1969 and that a rain event on it caused it. I suspect that this was the same storm cycle Johnny and Guy Waterman goy caught in which I read a story about. 9:30 Pinkham Notch: +1.0c , sky Few, Winds L-West, precip: Nil. Large crowd. 11:10 Harvard Cabin +4.5, snow on ground was firmer, Wind L-West with occasional Moderate gust. 13:30 Floor of Huntington Ravine: TAir +3.0c, Sky Scattered, Winds L-West with occasional Moderate gusts. No results with an ECT. Shovel Shear test result was hard, Q3, 10cm down.

Snowpack

Not very interesting except for the top 7-11cm. This was new snow on top of a MF crust. The top half of this layer was just moist. The bottom half of the layer on top of the MF crust was slush and grabbing a handful of that and squeezing it produced a small stream of water from it. This was a good example for the class of a wet slab issue. Snow temps were as follows: TSurf: -0.5, 10cm down: -0.5. 20cm down: -1.0. 30 cm down: -2.0, 40cm down: -1.0, 50cm down -1.0, 60cm down -1.0. 11-26cm down: P, 26-41 down P+, 41-56 down P, below 56 down 1F.
