I took a look at the snowpack above Miller Flat on a north facing slope at 9850'. Overall, I liked what I found. Two things interested me.
- Status on weak sugar snow near the ground
- Any weakness in the mid portion of the snowpack from the dry period in mid December.
I was pleased with what I found near the ground. There was a small amount of old faceted sugar snow from early in the season. This layer has gained a lot of strength. I was still able to get it to propagate in Extended Column Tests but I had to force it with my boot before it would fail. Combine the strong bridge of snow that is above it and it seems quite unlikely that this is going to cause avalanches.
Looking at the layer of snow from mid December, it showed small faceted grains although they didn't alarm me at first glance. I performed ECT tests on this layer with no results. I did get all of the snow since the week before Christmas to fail and propagate (ECTP-25) above the layer I was concerned about. The failure did not involve the layer of snow I was looking at but rather failed on a wind crust above it. I am not all that concerned about this minor weakness. My hunch is that it will strengthen fairly quickly and won't pose a long term threat.
