This map was issued with William Henry Sidell's "Survey of a route for a railroad from the Great Bend, on Red River, to Providence, on the Mississippi River." It shows several routes to be examined from the Mississippi River to the Louisiana/Texas boundary and depicts early county and parish configurations. The Bastrop Claim is shown extending into Arkansas.

William Henry Sidell (1810-73) was educated at West Point, and turned his attention to civil engineering at a time when the railroad system was first developing. He attained the rank of Brevet Brigadier General for his services during the Mexican War and the Civil War.
