The northern edge of Marathon and its adjacent islands define this maritime landscape in the Florida Keys. Centered on the transit corridor of the Overseas Hwy, the map documents the narrow ribbon of developed land and recreation paths that link Crawl Key, Little Crawl Key, and Grassy Key. Beyond the land, the survey focuses on the shallow marine environment, identifying key navigation hazards and landmarks such as Coffins Patch, West Turtle Shoal, and East Turtle Shoal.
