We walked by the lighthouse after finding a nearby cache. I quessed later that it was a benchmark.

Many walks by this, never knew it was a benchmark.

It's been a year, almost. Time for another log with the obvious "it's there!" and a photo.

I viewed this cute Lighthouse from the NJ side of the river.

Of course it's there.

If you haven't read "The Little Red Lighthouse and the Great Gray Bridge" by Hildegarde Smith and Lynd Ward to your children, you are missing a modern children's classic. This book, written in 1942, is credited with saving this structure from the junk pile.

Interestingly, this lighthouse was originally used at Sandy Hook, New Jersey as a fog signal from 1880 when it was built, until 1917. It was then taken apart and 4 years later was reconstructed at its present location. This was one of only two lighthouses that were operated on the island of Manhattan. It was decomissioned in 1948.

The other one has an equally romantic and inspiring story and it too was saved from the junk pile through public concern. Do you know where it was? It served from 1913 to 1967. To find out, see [url=http://www.geocaching.com/mark/details.aspx?Pid=KV4367]The other lighthouse[/url].

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in January 1999.
  • The orthometric height was scaled from a topographic map.
  • The Laplace correction was computed from DEFLEC99 derived deflections.
  • The geoid height was determined by GEOID99.
