Something a little different

[Older The Better]

Thought I’d try a hole at my newest site. It’s small but productive. I haven’t worked out the extent of the site yet. I set up 8’ from a productive area and came up with a couple flakes. So I moved back and dug next to a previous hole that was productive and had a winner.

I’ve taken many pictures of lots of round corners of rocks in the ground before. Finally got an insitu of a grinding stone. Aside from only being the 3rd one I’ve found it’s kinda cool that it’s broken and being held together by clay.

Also a grinding stone is a good indicator of what kind of site I’m on and has me hopeful there’s more artifacts to be found there.

And one showing the other flakes across the bottom, few fossils on the left and a few rocks at the top that turned out to be pretty iffy/nothing when cleaned

Nice Mano probably cracked from freeze I would assume

I don’t know if the mud will hold forever but I kind of like it that way, figure if it falls apart I’ll clean it off and glue it

Out of a very small sample size, 2 of 3 are made of this red sandstone that takes a smooth polish texture. Got me wondering about them. Did they heat treat a specific sandstone to change its properties? Is it possibly a low grade quartzite? Seems they had a preferred stone to use for grinders which is interesting. Mostly Just wondering out loud but any insight is welcome, like I said I don’t find many groundstone artifacts.

I’ve found some heated some not

I have never seen heat treated sandstone.

not saying it may not have occured.

I would think that the red hue in sandstone would be due to the chemicals laid down with the sand prior to being metamorphized to stone.

Quartzite turns red when heated

I don’t know if it’s really a heat treat but sandstone around here that’s been in a fire turns brick red. I tried to look closer but even the broken faces have patina I’m guessing it’s a certain layer of sandstone. Some were strong enough to be used in buildings other layers you could crumble with your hands

I’m guessing what I find is quartzite it could be sandstone I know we have both here. It’s a very nice example of a Mano/grinder

It was a rare cool July day, went back out mostly just to be outside, set up next the hole I found the grinding stone in, I found nothing but a handful of flakes but I thought while I’m here why not look for that last piece… surprisingly I found it, now it’s just missing a little flake but I don’t know if I’m willing to look for that needle in a haystack… color difference is just from cleaning the last piece

That's not clay. That's Native American super glue! Nice find.

It is doing a surprisingly good job of holding it together, I thought it may dry out and fall off but not so far.

the red in heated stone comes from iron content. I doubt if sandstone was ever deliberately heat treated, but plenty got burned while in fire pits. Iron rich clay turns red as well if heated.
