1921 Map of Sugar Loaf Key

USGS Topo · Published 1942

About this map

Sugarloaf Key and its surrounding archipelago dominate this tactical reconnaissance, which details the intricate landscape of the lower Florida Keys before mid-century development. Grounded in surveys by Col. W. M. Black and 1st. Lieut. Harold Geiger, the chart documents a maritime environment defined by shallow sounds and mangrove-lined passages. Small early settlements like Big Coppitt and Stock I. are visible alongside the rail alignment that once connected these remote outposts. The map provides essential hydrographic data, including soundings across Sugar Loaf Sound (Lower) and through the Boca Chica Channel. From the northern reaches of Johnstons Key in Florida Bay to the southern waters of the Straits of Florida, the document tracks the natural geography of Cudjoe Key, Snipe Keys, and numerous smaller islets like No Name Key and Eagles Nest Key.
