These four maps show the surveying efforts in the area about 25 years before the Cape Cod canal was established in 1914. The map of Provincetown identifies the high and low water lines, shows numerous soundings and docks, and was drawn under the direction of Lieut. Col. S.M. Mansfield of the Corps of Engineers in 1896. The other three maps demonstrate the shifting shore lines and were included in the 1889 Coast and Geodetic Survey report.
