This was the critical map of the boundary survey. Initial negotiations had broken down over a Mexican demand that Mexico be given the port of San Diego and the determination of the length of a league. It provides interesting detail in the vicinity of San Diego and along with its companion map of the Vicinity of the Gila River determined the anchor points for the new border. The map is full of interesting information and is visually attractive with calligraphy title and a large compass rose.
