This 'tour' is divided into two sections. Mill D used to contain a power plant of its own, most of which has now been torn down. There is a relatively small building that still stands that seems to be related to the Mill D power plant, given the electrical gear that it contains, and given its proximity to the former power plant's smokestack. It is unclear whether this powerplant building is or is not actually connected to the rest of the Mill D complex, but even if it is, the area of the building in which the connection would be made is too dangerous to enter. Therefore, we entered this building through one of its outside entrances, and accessed the rest of the Mill D complex through a different entrance. Given this fact, I have made separate pages for Mill D and for its power-outbuilding, both of which may be accessed below.
