Wear long pants and sleeves and check your skin and clothes frequently for ticks.Use an appropriate insect repellent containing DEET.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.
The tiny deer tick can transmit Lyme Disease and other illnesses, so you should try to avoid brushy areas or leaf litter where these ticks may be abundant.
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.
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.
