Squirrel Hollow Road Quarry in Pottstown Pennsylvania
Amazing how a bit of altitude can make a once large object, such as a dump truckor or trailer, look like mini models that you give to your kids to play with in the dirt and sand.
Lots of hard work and heavy machinery is needed to cut the bedrock in such a manner, yet also creates a lot of potentially hazardous dust as a result of the obliteration process for the locals.
