This detailed map was published by the American Geographical Society. It covers the region from the Bohai Gulf and Beijing west to Lanzhou and Qinghai Lake. The map shows the series of fortifications that compose the Great Wall along with the routes of Clapp, Fuller, Barnett, Estabrook, and Herald who explored this region in detail. Includes two inset maps: "The Palisade, an Extension of the Great Wall in Manchuria" and "Ancient Extension of the Great Wall in Northwestern Kansu." Signed in the plate by William A. Briesemeister.

Founded in 1851, the American Geographical Society was created with the specific intent to rescue the missing Arctic explorer Sir John Franklin, believing that he was still alive in the Arctic Ocean. Despite the unsuccessful search, the society continued on with its core work centered on explorations, surveys, and related publications.
