It is kind of a conundrum, this realization that dwindling snow piles are actually a sign of spring. South of Harbor Beach, there are bluffs that run along the shoreline. Not really like the swales (long sandy berm type geological features) that are found on the Saginaw Bay side of Huron County, these bluffs might have been the shoreline for the "old" Lake Huron, before the last glacial cycle.
Because the bluffs face east the snow gets morning sun, during the much colder part of a spring Great Lakes day. The ground temperatures stay cold and bluff snow melts very slowly, as you can see from this photo that shows green grass, blue skies, and one very large patch of snow, still dwindling.
