Observation: Summit

Location: TenderFoot/Fresno

Route & General Observations

We toured up the Tenderfoot uptrack to 2500′. We were curious how overnight winds had affected surface conditions. We did not observe any wind effect in the surface snow at our elevation band but noted textured snow higher in the alpine.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

We observed consistent light snowfall accumulating an inch between 12 and 430. Winds were calm and skies were overcast to broken. A layer of valley fog developed around 2000 ft in the afternoon.

Snow surface

7" of new snow from yesterday's storm remained undisturbed by wind up to 2500 ft.


We dug snowpits on a west aspect at 2500 ft on Tenderfoot as well as 1700' on a SE aspect of Fresno. Our layer of concern was the interface between the January drought layer and new snow from the last two storm cycles. This was buried 25-30 cm deep. CT test yielded resistant planar breaks after 3-12 taps. ECT tests showed no signs of propagation. Buried surface hoar was observed between the drought and storm snow down 30cm in one pit.
