Vermont Marble Quarry, Abandoned Mine Site, Limestone Hills, 2.25 miles Northeast of Radersburg, Radersburg, Broadwater County, MT
- Upscale 2x7680x6110
Significance: The quarry was the only place where Meagher limestone was quarried. The gray limestone is mottled with yellowish-orange spots and was marketed as "Montana Black and Gold Marble." It was used for facing stone on a number of public buildings in Helena, as well as being sold on the west and east coasts. The mast for the "J-rig" derrick was reportedly the largest single timber ever shipped into Montana. Although in operation for only a brief period of time, the quarry produced a somewhat unique product for Montana.
