If you have not been to Big Hill you should take the time and go there. You must stop at the guard house and tell them you are visiting "Lookout Park Nature Center."
Follow Huntington Drive for .8 miles and turn right on Kingston Way. Go .15 miles to Gramercy Place and turn left. Travel .35 miles to the Nature Center at Lookout Park on your left. There is a dirt road in but it says no vehicles, and I parked on the road. There are senior citizens homes there so be respectful. Walk in to your left toward the gazebo, the tower foundations, the markers, and then the lookout view.
This is the foundation for the fire tower that is shown in Boyds topo. The geodetic monument is in it just above the word "Forest. There are others in the area if you look for them.
