That was what I noticed too, and likely good for making an igloo.
Hans B and Aaron Glazer made them &/or snow caves years ago in the Pinkham Notch area. I think it was an AMC class or something similar.
I was an ADK/AMC winter mountaineering school instructor for about 10 years, in both the Whites and then the High Peaks in NY. We built igloos in the Great Gulf and spent 4-5 nights in them. Takes about an afternoon to construct and you get quite wet. As lodging, they warm to freezing inside, which is very snuggy when it's -10F outside.
