BASALT

Basalt is by far the most common rocks you will find on Lake Superior’s North Shore beaches. It is one of the four rock-types that make up the basement bedrock of the earth’s crust. Basically it is lava that cooled quickly on the surface. Each one has a distinctive shape and in a variety of shades of color from blush-black to grey. That quick cooling is what caused it to be dense, very fine grained (tiny crystals) and smooth – although the smooth surface is also due to glacial grinding & Gitche Gumee tossing it about for eons. That Basalt rock you hold in your hand (or wear on your body) is over a billion years old!
