Split-wedged rock from the WHOI Quissett Campus

Another find from my walk in the woods at the Woods Hole Oceanographic Institute Quissett Campus was this fine split-wedged rock. From the damage along the edge of the upper rock I guess this was split intentionally, perhaps starting from a natural split. Split-wedged rocks are very rare down here on the Cape and, in fact, this is the first good example I have seen. FFC found some in the past by digging into the fill in enough split rocks. But this one was easily visible. As I came up to it, I saw a split and hoped to see a wedge - there is was.
