GT1509 - D 363 Revisited

This benchmark was first originally visited on January 2, 2004.

I drove by this location a few weeks (months) ago and noticed that things had changed.  The biggest change, although not the most immediately obvious, was that the fence had been replaced.  Along with its replacement was the removal of the view-obstructing, wood slating, as it was now easy to see the airport and runway.

I was able to stop to get some pictures today and was surprised to find GT1509 - which had been outside of the fence - now inside the fence.  At least a portion of it.  I can only assume that the mark was moved/damaged/destroyed by the fence construction crew.  I'm unsure as to why they did though.  As far as I can tell, the fence alignment didn't change, the mark was not in the way of the alignment, and the mark's concrete setting was flush with the ground.  It shouldn't have been in the way of the fence crew, and truthfully, it may not have been them.  Regardless of who, the result is the same.  This mark has been severely damaged, possibly destroyed.

The mark itself is still intact in its concrete setting, although the setting has been uprooted and the top 15 inches or so have been broken off.  The mark and the top portion of the setting is and now resting inside the airport fence along with some other small pieces of concrete which most likely were for the Rotary International sign referenced in the original description, and seen in the pictures from my first visit 11 years ago.

Found details for Benchmark: GT1509
This mark has been uprooted and the top 15 inches of the concrete post is now resting inside the airport fence. The referenced Rotary International sign is now gone. Smaller pieces of concrete lying nearby looked to by parts of the sign's foundation.

A portion of the airport fence looks as if it has recently been replaced. The old & new fencing materials can be seen in the photos. Damage to the mark most likely happened at that time.

No new coordinates were taken.
