The steel tower this light was on was destroyed a long time ago. Therefore, this mark is also destroyed. The mark is NOT the lighthouse.

Logging another benchmark in this park. In 1926, the 60 foot steel light tower was built on the river’s edge, 100 yards from the Lighthouse. The steel tower was torn down in the late 1930's.

Have visited but drove by and viewed from Belle Haven today.

I'm going to echo what was said in the last log. I'm going to log it as a find

Found the piers that used to support the old lighthouse. Not a chore and probably doesn't rank as a find because there are no identifying numbers on site for the old lighthouse. But, I'll log it anyway. Canuman. Visiting from Greer, SC.

This benchmark is destroyed because the tower is gone.

The four cement foundation posts of the former navigation light tower HV4638 are shown in the picture. Each has some steel remains of the tower. The nearest is the smooth square-conical concrete base with steel remains on it near the center of the picture. At the far right of the picture is another base. In the background center is a third concrete base. The fourth concrete base is seen near the center of the left edge of the picture, but it is covered with vines. The view is to the Northe

Control Text

  • The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in November 1994.
  • 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.
