It has not snowed more than a few flakes on Cape Cod so far this winter. My mom, B and I stopped by Skaket Beach to say hi yesterday and this is what we saw. It was like a scene out of Rudolph where Yukon Cornelious cuts the iceberg and floats away with Herbie and Rudolph.
I would love to give you the scientific reasoning behind big ice flow blocks on the beach, but I do not have one. So you will just have to enjoy an interesting part of nature!
