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

Cold temperatures down low today with calm to light winds. Some high clouds but mostly sunny

Snow surface

Surface hoar up to about 2000'. Then we got on a wind affected ridge and did not see it at upper elevations. Mixture of soft snow and wind stiffened snow at upper elevations.


We dug in two locations, one on a SW aspect of Magnum at 3400' and one on a N aspect of Cornbiscuit at 3000'. We found the layer of facets on the ground in both locations but they were moist enough to make a snowball. On the N aspect the facets were larger and more developed but did not show propagation in our extended column test.
