Snow surface

1" of soft snow over a stout but breakable crust at the car, increasing to 4-6" over a thin crust at 1500' - above this the crust goes away completely, with ski penetration of 4-6". Soft snow along the entire route, including at ridgeline where even wind affected locations had 1-2" of soft snow sitting directly on the New Years Crust. Surface hoar - larger at low elevations - was seen in wind protected areas along the route.


Dug a pit just after the trail breaks out above the dense trees - see profile below. Of the three compression tests that had results, the two that had the most pop were rounding facets just below the New Years crust. The third failure - in small rounding facets above the crust - was much more subtle. No result in the ECT.
