Route & General Observations

With the low ambient temperatures, inquiring minds were looking for facet formation in the snowpack. At this elevation 40 cm is the total depth. Higher elevations measure much more snow, (up to 220 cm on Troy). A fragile layer 10 cm down broke easily, 3 taps, sluffing the stale powder and facets which would be a weak interface for new snowfall. Of equal concern should be the density of the block (30 cm thick here and strong enough for building a solid GOT Ice Wall) and the ground surface, where adhesion was minimal and snow grains were large, round, and wet. Grain types and densities in this pit should be considered estimates only. The route could use some alder trimming.
