This detailed mid-19th century map documents the progress of federal land surveying across the state of Iowa. Sectioned townships are filled with small symbols and letters reflecting their survey status, ranging from blank (not started) to C (platted and copied, with field notes recorded and transcribed). Survey lines, geographic features (mostly rivers) and a handful of scattered settlements are labeled throughout the image. Of particular note are Fort Des Moines, the important landmark of Council Bluffs (with the nearby outpost of Kanesville and Trader’s Point), and rapids along the Mississippi River (geographic barriers to a lucrative trade). The image was approved by Surveyor General of Iowa Warner Lewis. Published in Washington in 1854 to accompany a Congressional Report by the General Land Office.
