The BATTLESCAPES Marsh is designed with the same concept as our ponds/lakes. They are based on 1/8" MDF and have a surrounding embankment approximately 3/8" high. The body of the marsh is covered with smaller 1" and 2" landings for ease of movement for your miniatures. BATTLESCAPES Marshes are available in an 8" diameter or 12" diameter. The one pictured below is an 8" diameter marsh.
