Atlantic Ocean waters dominate this coastal survey of the Florida Keys, capturing the maritime geography just offshore from Marathon. The small landmass of Bamboo Key sits near the southern edge of the sheet, serving as a landmark for navigation within the Intracoastal Waterway. This transit route is clearly marked as it cuts through the open water, representing a critical artery for local boaters and commercial shipping in Monroe County. The map provides a clear look at the jurisdictional boundary between state and federal waters, defined by the Florida state line and the county limits, which curve through the open sea.
