The following descriptions and elevations are taken from reports of the Coast and Geodetic Survey, and are republished by permission of the Superintendent of that bureau. The bench marks were established from precise levels, by the Coast and Geodetic Survey, by the United States Lake Survey, by the New York State Survey, by the Board on Deep Waterways, and by the Corps of Engineers, United States Army. They were included in the 1903 adjustment by the Coast and Geodetic Survey and were not changed by the 1907 and 1912 adjustments. The elevations are likely to be changed only slightly by any future adjustment.
