It is the sound outside our bedroom window.
Over the last few days, the noise from the pit has been louder than normal. This is to be expected, due to the fact that they are moving closer to the subdivision. Right now, I suspect, they are removing overburden from the cells closest to the subdivision. And it is loud.
I recorded the following audio using a voice recorder app on my cellphone. It was placed in my bedroom window, approximately 1200 feet from the pit. This is pretty typical for the sound coming from the pit, especially in the last few days.
