Sketch of the Sabine River Lake and Pass from Camp Sabine to the Gulf: Eaton, 1838

This elongated hydrographic chart depicts nearly 300 miles of the winding Sabine River from the interior down to its marshy outlet on the Gulf, combining soundings, navigational notations, and inset views of Sabine Lake and the complex entrance channels to guide mariners from upriver camps to open water. Two insets at lower left— “Sketch of the Channel through the Pass” and “Sketch of the Passage through the Raft”—supplement the main course, while Eaton’s marginal notes record notable riverine features, preferred routes, water depths, bank elevations, and magnetic variation.

The map was issued as part of Major W.G. Belknap's 3-page report (not present) to the Secretary of War.

Background on Creator

J. H. Eaton was likely a technically trained surveyor–cartographer working in a governmental, military, or engineering context, producing practical riverine charts that emphasize navigational hazards, soundings, and route annotations rather than decorative elements. His work on the Sabine suggests familiarity with hydrographic surveying methods of the nineteenth century, including the use of compass bearings, measured distances, and observational notes to compile elongated strip-maps for pilots and engineers.
