Went for a hike up the South Fork Drainage to San G yesterday (Sunday 11/24/2019) to scout snow conditions. Here are some highlights:
- 4-6 inches of snow consistently down to 7,000 ft and patchy below—only on shaded aspects. Up to a foot in isolated locations above 9k.
- Surface hoar (frost) on shaded aspects above 8-10k ft.
- Minor temperature crusts on snow with sun exposure.
- Dug a “pit” at 10,000ft, height of snow highly variable, but averaging around 13cm.
- Snow was mixed form, about half was decomposing facets, the rest (especially near the bottom) was 1mm facets.
This pit showed a perfect example of a CRITICAL temperature gradient in an early season snowpack.
(For reference: critical temperature gradient = Greater than 1*C change in 10cm which equals faceting.)
Pit height: 13cm
Air temp: 3.5C
Surface Temp: -9C
10cm Deep: -4
Since we can assume that the ground is close to 0C. Therefore we know that this snow is actively faceting.
