In all of my stumblings about Roundrock, I have never come across what I would consider to be flint. As with most other subjects, I am no expert — in rock identification in this case. Yet I think the stone above may be flint or something close to flint.
I came upon this rock in the area of the lakebed where the builder had found some clay to use for packing against the leaky dam. A great swath of ground was shaved clean, and it is only now, years later, beginning to sprout plants. (We had tried seeding grass there several times, but the stuff never took root.) Anyway, with all of this exposed soil that stayed relatively exposed, Pablo thought this might be his best area to search for those elusive arrowheads. I’ve not had any luck — you’d know it if I did — though I have scoured this bit of land many times.
Thus I was surprised on my last visit to find this brightly colored bit of arrowhead raw material emerging from the ground. (Because this exposed soil won’t grow any plants, much of it is being washed into the lake when the rains come. Although not as good as Bentonite, I’m hoping this clayish dirt is helping to seal leaks. I may be naive.) It’s a bit hard to tell in this photo, but this stone sits in one of the rivulets that form on the exposed hillside. I think this stone may not have been above ground until recently, which would explain why I had never seen it before despite my repeated attentions in the area.
I carried the rock (it’s not so big) back to the shelter so it could be a kind of decoration there. But I’ve since wondered if it is one of a kind. Does it have flinty friends beneath the soil across the lake where I found it? I’d be surprised if there was a seam of flint between my limestone bedrock and the sandstone cap (though the round rocks fall in this middle area, and I’m not sure how they found their way there either). More surprising to me, however, would be if there were no other samples of this type of stone at Roundrock. That would mean that the individual stone was brought to the area from elsewhere, of course by human hands. So then I fall into the realm of my wild and indulgent speculation. Was this carried by some First People as raw material for making tools? Was its place there in the ground an indication of an old campsite? Should I redouble my efforts in that area to see if there is something else left behind by those long gone?
It’s stuff like this that keeps bringing me back to the woods!
Housekeeping note: Tomorrow I host the second Festival of the Trees. It’s a big’un, and I’m pretty sure all of the links work.
