- Sign describing the Mahogany Hammock in the Everglades National Park.
- Photographed in December 1973.
- Note sign reads, "Signs of the Sea Mahogany Hammock lies close to a transition zone where fresh and salt water begin to merge. Between here and Flamingo the waters become increasing saline as they flow toward Florida Bay. This sharply influences the landscape, and the character of the vegetation changes completely."
- The Mahogany Hammock Trail is a self-guiding boardwalk trail that meanders through a dense, jungle-like hardwood hammock. Vegetation includes gumbo-limbo trees, air plants, and the largest living mahogany tree (Swietenia mahogani) in the United States.
