Here's a remarkable photo of a once-thriving business in Bluffton: The Woodcock power plant. For residents of Bluffton since 1983 or so, this plant was located on the site of John's Body Shop, Lake Street. This photo was taken in the early 1950s.
There are several things to notice. First, count the railroad coal cars on the AC&Y Railroad siding. The plant was fueled by coal and that may be a one or two-day's worth of fuel sitting there.
Notice how clean (absence of trees and brush) are the banks of the National Quarry.
