Everyone knows strip mines are big places. I mean, they're what happens when you turn mountains into lakes. But it doesn't really sink in until you actually see one.

There's a vastly smaller open-pit quarry down the W&OD bike trail. For whatever reason, the builders of the trail made a nice overlook into the main quarry, which is probably a half mile across and maybe a quarter of that deep. Still, quite impressive to see the tiny trucks with their six-foot-plus wheels creeping around like tiny Tonka toys.

I can't imagine what this thing must be like.
