I drove here to figure out why this huge area owned by Berks County Parks had no caches on it. Looks like it is a water shed area (probably for Wernersville). There is parking right at the GZ.
Mind the signs that say it is a federal offence to trespass here. There are two columns here that stood as a gate before some ancient building. If you look past the trees and brush you can make out the remains of something made of stacked stones along the steep grade behind and to the right of these gates. Look but don't trespass.
