✅ SOLVED Indian Artifact or Rock?

[Crispin]

Find this in an area well known to be associated with Native Americans. This thing stuck out like a sore thumb. Nothing like it anywhere... If rock, anybody know what type?

Rock. We call them cobblestones.

Okay thanks. Looked liked something you might find at Lowe's to put around a yard but I wasn't sure.
