This aerial view of a slate quarry in Monson shows the quarry pit to the right of the photograph along with various types of equipment used for quarry operations and the quarry mill. The building and quarry was owned and operated by the Monson Maine Slate Company.
The quarry mill is the long L shaped building in the image. It later became Moosehead Manufacturing in 1947. As of 2012 this building is still standing, though abandoned.
Also, of note is the large piece of equipment in the right foreground of the image, called a hoist. The hoist was used to raise and lower both men and slate in and out of the quarry. The mined slate would be sorted and the high quality pieces would be brought to the mill for processing and shipped out by a narrow gauge train.
The writing across the bottom of the photograph reads "Slate Quarry, Monson, Me. No 28" This image is labeled as 28 because it is part of a series of images taken of the quarries.
