Okay one more.

Curious what causes the formation of the little white rocks . They are all over the area of Arkansas I'm in ( Ozark area).

That's a conglomerate, remains of an ancient river.

That's so cool. Now I can explain it to my kiddo. Thanks

I dissected one of the rocks today. Once I was able to break one in half , no easy task, there were several layers. Top seemed like burnt crust (black lava like) , then reddish sandstone ( could slowly remove with toothbrush and knife),and a few empty pockets of brown clay. A lot of the white pebbles and many other color, shapes, and sizes of little crystal like stones. I'm saving all of them.
I'll work on the others throughout the week.
There are a few larger ones in the woods behind the hotel. If I could somehow grab one I would .

I think that's what you call curiosity, huh?
The layers where formed in the river, during floods (= bigger rocks) and during times of low water (= clay).
If you'd start digging in a modern river I think you'll also find layers similar to that rock.

Just as a note, that was not sandstone.
The whole rock is called conglomerate, sand is quite common in rivers, so it'd not be surprising to find it in river sediments gone rock-solid.
Actually, conglomerate is one of very few rocks with rounded rocks in it, typically a tell-tale sign.

Yes, my curiosity tends to get the best of me at times. Hands are sore but ready to get at it again.
Not sure why I said sandstone , meant sand. That's how one layer looks when brushing away the material.

It's good, curiosity is a must in this hobby.
