A letter from Norman

When you mention “cavities” below, I thought of one of the engravings in a Smithsonian publication of a stone mound in West Virginia (attached). You must know that I’ve found a number of “tails” or extensions of the large platform cairns I’ve documented in Vermont. And that all began with a single platform cairn at the Oley Hills site in Pennsylvania. Attached is an image of that “tail.”
