Visited Dry Tortugas with Beburn. Beautiful and amazing that such a large structure stands in the Gulf. Would love to come back and camp for a couple of nites.

Recovered in good condition.

Visiting light house.

Wonderful trip out to the island, and snorkeling while there. Disappointed that the rangers didn't have a nice stamp for the lighthouses for my passport book though.

Al's sister & husband took us here and we had fabulous time at fort. While we walking around the fort I looked down saw this benchmark in the middle of the moat wall.

Found on a walk of the Fort. My son's Boy Scout Troop camped at the Fort for 3 nights. It was a great experience and I would love to come back with the rest of the family. My son is the second from the left in the picture.

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in May 1991.
  • The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
