These are a few of the rocks I found while walking on the Lake Michigan shore. I always look for heart shaped rocks and wasn't disappointed this time. As you will recall from Geology 101 [which I barely passed with a C] these are predominately igneous rocks [the others being your metamorphic and sedimentary types]. Below are some good examples of the variety of 'wash up' I found, including two pieces of sea glass...most likely old beer bottles...plus wonderful little shells and fragments of shells.

Even little children love Marianne
Down by the seaside siftin’ sand
from the 1950's song 'Marianne' by Terry Gilkyson, Frank Miller and Richard Dehr
