Day 7.255: Wolfe's Neck rocks!

There is a small sandy beach that can be accessed from the trails at Wolfe's Neck State Park, but for the most part, the shore there is rocky - and these are some interesting rocks.

I'm no geologist, but I could recognize that these angled slabs had probably formed lying flat. They are now nearly vertical in places.


More surprising still were these stripes, cutting across the layers of rocks and presumably therefore through many hundreds of years of rock formation history:


It turns out that they are probably dikes - narrow intrusions of other rocks - formed long after the original rocks by igneous or sedimentary rock filling in a crack in the older rock.

As with many natural things they look almost too strange to be natural!
