What the Heck did I just find?

Actually I was gifted this stone from a local that was moving and he had do down size the collection. My friend said that this stone was found in the UP, but not 100% confident. I posted to a few groups, asked a few friends and came up with the following conclusion. Banded Basalt? An igneous or coming from lava, which could explain the banding and liquid like look. Anyway, very cool stone that I am Happy to have added to our collection. Here are some Pics!
