The office/bathroom is inside this building, and the first building in the album is visible through the trees in the background.
Burned Steps
Even older looking stairs - the mine has history back to the 1800s, but this is probably not that old. The building on top of it appears to have burned, leaving behind electric wires and boxes.
Entrance
Entrance to the facility - and my car!
Machine Shop
Judging from the abundance of 440 volt hookups in the building, this likely was some sort of machine shop.
Overgrown

Benson Mines is a long-abandoned iron mine near Watertown, NY.
The mine was shut down in 1978 and the buildings and have been completely abandoned ever since.
Abandoned man-made structures are my favorite to take pictures of, so I couldn't resist exploring!
