Any pic's of John Ziegler's Riverside Mine buildings on Salem-Southeastern RR ? He had multiple mines under his company's name of Riverside. Others were named Ziegler's Bank, some in other counties. His first was likely pits west & north of Capital's Salem Quarry (north of state B & at CR 522) on the headwaters of the Meramec River (a creek there) in Dent County.
