White/gray material. Pottery? By-product of something?

In all of my travels I’ve only found stuff like this in one place. It is on a trail which crosses a dry stream bed.
There is a ton of this material.
Is it pottery? Is it the by-product of some activity at this spot in the woods?

Could it be a pocket of decomposing sandstone?

There is also a ton of this material on a slope in my backyard. I find it in a thick layer of ashes, and I find thinds that were obviously in such fires. I always thought it was some kind of byproduct of a fire bit I really don't know. I'll certainly keep my eyes on this one.

There are some small clay beds in these woods and I wonder if early Native Americans dug the clay and fired their pots at this one location.
