Almost anywhere we wander in New York, we are apt to encounter glacial erratics, rocks that were transported to their current locations by the great sheets of ice that covered the state as recently as 10,000 years ago. Typically we just step over, or walk around, these aberrant rocks. That is, unless we trip on them, in which case we curse their existence before we move on. Farmers detest them too, but will use them to build stone walls or cobblestone barns. Once in a while we might notice something interesting in them and stop to smack them with our hammers or mauls. Typically they resist such actions, providing us a reason to detest them even more.
But there are some really famous glacial erratic boulders in the world. Some are famous for their size, others for their location. Perhaps you have a favorite one? I’ve selected a few to highlight.
