This matched pair of maps covers the coastline from the mouth of the Rio Grande east to Key West. Western Part (23.0 x 28.1") extends from the Rio Grande to Terrebonne Bay in Louisiana. Along the way, Corpus Christi Bay, Matagorda Bay, Galveston Bay, Sabine Lake, and more are identified. Eastern Part (28.5 x 27.6") stretches from the mouth of the Mississippi River to Key West. Havana appears in the bottom right corner. Both sheets include many soundings, magnetic variation compass roses, notes, and table of abbreviations for bottom types with names of cities and islands along the coastline.
Issued folding with light toning along the folds. There are separations at fold intersections with minor loss and along some of the folds, some of which have been closed on verso with archival materials. The first image is a composite image - the map is in two separate sheets.
