Here's a picture from my New Year's travels. The Serpent Mound is in southeastern Ohio, near Hillsboro. From head to tail, its about 1/4 mile long and two feet high. In this part of Ohio, ancient native americans built many mounds, but few represent animals. This is the largest "effigy mound" in the world. No one is really sure when or why it was built. There are no burials in the mound. The picture shows the tail at left and the head just over the hill in the distance.
