Marvine Colliery, Dorr Thickener Plant No. 1, West side Boulevard Avenue, between East Parker Street & Route 380, Scranton, Lackawanna County, PA

Significance: Marvine Colliery is important to local history for its relationship to the development of the Anthracite Mining Industry in northeast Pennsylvania, "The Anthracite Capital of the World" 1890-1930. The Marvine Collier Dorr Thickener No. 1 is important to the history of the anthracite mining industry, as this type of thickener apparatus was rare in anthracite mining operations. Research indicates that this particular Dorr separator was the first of its kind to be constructed and used in Delaware and Hudson Coal Company operations. The Marvine Colliery Dorr Separator No. 1 is the only surviving example of Dorr separator silo architecture in Lackawanna County, Pennsylvania.
