Relief shown by contours and spot heights. ["Topography by photogrammetric methods from aerial photographs taken 1955. Field checked 1956."] NOTE: The bottom 8 centimeters of this map (which contained important identifiers such as date of publication, projection information, date of aerial photographs, etc.) was cut off at some point in time and presumably discarded. Information in brackets in this record has been gathered by using later maps of the same title (e.g., 1969, 1974, 1983, and 1999). ["N3337.5--W8407.5/7.5."]
