Today was a clear and calm day at mid and lower elevations. Once above treeline, moderate east winds were present and some snow transport was observed on the upper mountain.
Today I went out to investigate the distribution of 12/8 buried surface hoar on the north side of Mt Hood along the Tilly Jane Ski Trail. I dug several test pits on multiple aspects/elevations throughout the day as a way to see where this surface hoar lived. In some locations this weak layer was easily identifiable with the naked eye and appeared as a thin gray line in the upper snowpack. Other areas this buried weak layer was harder to find, but identifiable with snowpack tests. In 4 out of 5 test pits I received propagating results on this layer of buried surface hoar. Generally, this layer was found 12-15 inches below the snow surface and existed at lower and mid elevations. Once above treeline, this buried weak layer was harder to locate and snow surfaces were wind textured and firm.
Layer Depth/Date: 30-40cm
Weak Layer(s): Dec 8, 2022 (SH)
Comments: Distribution is specific to areas below and near treeline, especially in areas with without canopy ( meadows, open slopes). Still reactive with propagating results in test profiles.
