Follow Marty's Marsh around to an opening. A great picnic spot with lots of wildlife to see. Easily accessable depending on how boggy the ground is. The cache is in an old spice pot with a silver lid. A pencil, paper and coin are inside.
Edit:
Checked area and old cache appears to be missing so replaced with a plastic jar. New log and coin left as well.
