Stones

These are natural bricks of sorts. I found them on the north shore of the Far Away Island, where a seam of clay is visible in the cliff. The “blue clay” is part of the muck of the late Pleistocene glacial deposits that make up the island. The same stuff makes up the long island of Paumanok, underneath me right now. But these stones are obviously not just clay. Somehow the clay has fused together into a solid, albeit friable, form. I haven’t figured out how yet.

Is there a geologist in the house?

Nice how those look hand burnished, molded against palms, very shapely. My dad thinks they're probably claystone that's not well lithified.

Here's what he said about the one with the circles from your previous post: This isn't glass and I'm not sure what it is. Sure looks interesting though. I'd check with a paleontologist on this if I had it.

...Geologist William Melson, comin atcha from the Forte Valley, Virginia.

Awesome! There was a geologist in the house after all. Extend my thanks to the man.

The Museum of Natural History has an annual bring-your-stuff-in day, where pros ID natural history things, but it's always a children's event.

More from my dad, seems that glassy rock got under his skin. He's wondering if its fossil rugose coral.

Hmmm, he may be on to something here. I never considered this possibility. I've never seen anything else like it on the beach I found it on.
