Just 5 miles west of Antioch one can see the remains of the plant know as the Potash Reduction Company in a location referred to as Hoffland.
From The Great WWI Potash Industry of Southern Sheridan County, Nebraska by Clint Andersen:
Hoffland, though referred to as a town, was never incorporated. It was born purely of necessity from the Potash Reduction Company, the only plant in the area, and ceased to exist completely following the end of the potash run. The entire “town” of Hoffland was owned by the Potash Reduction Company from the men’s barracks to the laundry and the A-Muse-U Theater.
