Hello! Thank you so much for mapping stone walls. I'm working on mapping the historic town pounds of New England. Can you by any chance tell me if https://www.openstreetmap.org/way/1348641320 is the town pound of Lempster, NH? The LiDAR clearly shows a square-ish something there, but on the aerial imagery I can't make out the rocks that a pound typically would be made of. Since you called it a "retaining wall" I thought you might have an idea of what this spot actually is or was used for. Thank you!
