Rian's Quarry, located in Dickinson County, Michigan, is a smaller but notable locality within the state's Upper Peninsula, situated near the town of Felch. Geologically, the quarry was developed within the Felch Formation, a Paleoproterozoic metamorphic unit that contains layers of dolomite and marble. The site is known for providing a variety of minerals formed during the regional metamorphism of these carbonate rocks, often occurring in contact with iron-rich formations. Historically, the quarry was primarily an industrial operation for the production of crushed stone and aggregate.
