A very rare 1871 U.S. Coast Survey Map of Edgartown and Katama Bay on Martha's Vineyard, Massachusetts. This detailed working harbor chart was produced to illustrate the buildup of sand in the bay (making it unnavigable) in order to argue for the opening of a safe passage through Katama Beach. The chart shows the approaches to Edgartown - both the main approach from the northeast, marked by a lighthouse, and also the approaches via Katama Bay (Cotamy on the map)- whose mouth is shown entirely blocked by Katama Beach. Historical natural openings in the beach are noted, including a 1776 opening which had appeared on Des Barres' chart of the island, are noted. Nine cross sections of the beach are shown, indicating the height of the beach above sea level. A further cross section, showing the increasing silt blockage of the northern mouth of the Bay between the west shore and Chappaquiddick Point is shown as well. Tidal patterns measured inside and outside Katana bay are compared in a chart. Detailed soundings are provided throughout. (more details)
