Observation: Hatcher Pass

Location: Microdot

Route & General Observations

We went to see if any of the persistent weak layers would still be reactive in snow pits. Surprising soft snow in places if you can avoid rock hiding below surface.

Snow surface

The snow surface is still highly variable, but in wind protected areas low density snow could be found. Some wind pressed snow in areas from earlier in the week. ski pen 10cm. Ski quality was surprisingly good if you can avoid rocks and old tracks.


We dug two snow pits on microdot today, poor structure was found in both pits. The snowpack has moderate strength and still has some propagation potential, with the 11/6 and 11/22 layer both propagating in PST's. Some striation could be observed on 11/6 facets. Both pits had tons of facets and chains of depth hoar could be found near the ground in both locations. The MF crust that was the bed surface in the 12/29 avalanche was not found in second pit on south aspect.
