We got over 1” rain this morning; hard and fast. Afterwards I walked one of my fields where I’ve found artifacts, big pieces of granite, etc. This rock caught my eye due to the color. It is light gray and looks like a piece of hardened grout for tile work. On an unglazed tile, it leaves a white mark. I want to try to shape an arrowhead out of it. I lean toward it being sandstone, but it just doesn’t match up completely with any I’ve seen. This is less “crumbly” and that gray color seems wrong. Any help? Thanks
