Last week on the boardwalk I noticed footprints........frozen.
I believe these are formed when after a snowfall
someone walks through the snow which compacts
under their weight.
Then the footprints freeze and the rest of the snow blows away
leaving the footprints intact.
Just another one of those interesting phenomenons that
happens here in the Northern Hemisphere in winter.
These remind me of fossils which have been petrified.
