Washington D.C. Published by the United States Coast and Geodetic Survey, March 1922. Large folding nautical chart, printed on heavy paper stock. Colored. Sheet size: 35 x 45 1/4 inches.

A rare original coastal survey of southwest wetlands from Calcasieu Pass to Constance Bayou and including Pecan Island and the Mermentau River.

Established by President Thomas Jefferson in 1807 as the Survey of the Coast, the U.S. Coast and Geodetic Survey was the United States' first civilian scientific agency. This agency has followed its mission to survey the U.S. coastline, create nautical charts of the coast, and help increase maritime safety since its founding, and has often played fascinating roles in significant chapters of U.S. history. It served in all theaters of the Civil War in the service of the Union Army and Navy, pioneered acoustic exploration in the wake of the sinking of the Titanic, and during WWI it worked to detect enemy submarines. In addition, this agency worked to survey and produce detailed maps and renderings of the U.S. coast. These nautical survey maps (commonly referred to as "T-sheets") provide fascinating insights into the history of the United States coastline, which has and will continue to shift. These maps are the most important data source for understanding the physical and ecological characteristics of the U.S. shoreline. The present map is a highly detailed and accurate sea chart of the wetlands from Constance Bayou to Calcasieu Pass, and an important historical view of the developing Louisiana.
