I have a question. About a mile north of Martha, on Martha's Pond, there is an old ruin, high on a hill above the pond. Can anyone tell me what it was? It doesn't seem all that old, mid 1900's maybe. Follow the road north of Martha, bear left to go towards the rtiver, and you come to it. If you are paddling the Oswego, it's about half way into the pond, on your left. All you see from the river is the sandy beach, but walk up the road a little and you can't miss it. I'm also curious about the wooden bridge just south of the pond, near Martha. How old is it?
