Soldier Key and the northern reaches of the Biscayne archipelago stand at the interface of the Atlantic Ocean and Biscayne Bay. This 2012 survey details the complex maritime landscape of Miami-Dade County, focusing on the small islands and underwater hazards that have long dictated navigation in these tropical waters. The map highlights the narrow pass known as The Keyhole at the northern tip of Sands Key, adjacent to Boca Chita Key. To the north, the chain continues through the Ragged Keys toward the distinctive Safety Valve flats. Significant shoals and submerged features such as Featherbed Bank, Black Ledge, and Bowles Bank define the local hydrography, illustrating the shallow, shifting nature of the bay floor during the early 21st century.
