The green hoses visible in one photo are attached to pumps -- it appears the intent is to keep the newly created streambed (passing next to the dam) dry until work is completed, by dumping the water back into Toms Run just below the work area.
They are running dump trucks in and out of the area via the lower service road which has very large gravel added in places to support the equipment.
There's a 4' by 4' spring-head box south of the Steps to Nowhere and just east of the swimming pool (there's an orange flag placed by archaeology students).
Walk south from this spring-head box to see the ground lines from the Japanese fence addition.
Seeing the camp with so many dead plants is a little disconcerting, although this will make maintenance of the site much easier.
It also reveals more of the foundations and other remains of the old camp buildings.
Use an appropriate insect repellent containing DEET.
I guess there's not much else to say at this point... This fence ran south to north directly to the new guard tower added at that time.
I was searching this area for possible post-hole plates at the entrance gates to the Japanese compound similar to the ones at the German entrance.
What a difference to see the camp with the barberry and some of the other invasive plants all dead.
(Vince will be happy to know that Yountz Bridge is now visible.) The shrubs and stalks are still there but no greenery.
