Ironically, the land in the Hanford reserve is probably some of the most untouched land out there. Except for the radiation, but that’s mostly leaking into the groundwater & the Columbia. Or something like that.

Edit: There are Pygmy rabbits out there, and sage grouse, and more, all on hundreds of acres of untrammeled land! Hanford is a huge, unintentional experiment in land conservation.
