    I wonder what the inclusions in the rock are? I don’t think this is what it is, but the patterning reminds me of some obsidian with perlite I’ve seen before.

      From a geologist friend of a friend: Looks to be a pyroxene rich with olivine, or perhaps a basalt with olivine phenocrysts.

        From a friend of an “anthropologist” friend: looks to be DNA from one of the prehistoric giants that populated North America (bigger person equals bigger DNA).

    NW Florida. If I find a rock, it’s either a chunk of concrete or imported from elsewhere. Glaciers didn’t make it here. :(

      I suspect the glaciers did more harm than good for rocks. For example, up here they ground all our gold to dust and scattered it everywhere. You can find gold all over the place, but it got so spread out you’ll only get a few specs.

      It looks like Florida has several interesting things to venture out for including fossils, silicified wood, coral geodes, and agatized coral. I bet there’s an economical day trip you could make, and you don’t even have to wait for a spring thaw!

      This came from the New River, said to be one of the oldest rivers in the world. Older than the Appalachian Mountains where it starts and runs north.
