This quarry was located "in the town of Vinalhaven, on the north shore of 'Pleasant River' at the end of Winter Harbor, in the northern part of Vinalhaven Island." The operator was the A. M. Webster & Co. of Vinalhaven in 1905. Granite from the quarry was reportedly identical to the granite found at the Palmer Quarry. Transport of the granite was by "a graded track 200 feet to wharf admitting schooners of 300 to 350 long tons."
The quarry was abandoned at the time of the report. The granite had been shipped in the rough to be used for buildings in New York and Boston.
