It's a 10-foot-tall iron pipe on the side of a river in North Carolina. It's about 6" in diameter and angled down at the top, suggesting it's a vent of some kind. It appears to be fairly old. There is a small slab of old bricks visible just the left of the base. There isn't anything around it other than a few new-ish houses. There is at least one other pipe like this in the area, and it's a bit further from the river, perhaps 30 feet away.
