Battlemap Sandy Beach

Publisher's blurb: This is a 25 x 20 battlemap optimized for use with roll20.net. The Sandy Beach map is set on a secluded seaside beach, littered with shells and beach grasses. The beach dunes offer plenty of places to hide, and can be difficult to travel through the soft sand. Is there sinking sand on the beach? The party will need to be careful or they might find out!
