This quarry was "in the town of Frankfort, on the north spur of Mount Waldo, 660 feet above sea level, one-third mile southwest of Frankfort village." The operator of the quarry was the Mount Waldo Granite Works of Frankford, Maine. Granite from the quarry was reportedly a medium gray color. Transport of the granite was by "two graded tracks, each 1,200 feet long, operated by gravity from the quarry part way down the hill to the power house, thence by a cable road (Roebling engine) 1 ¼ miles to the wharf, which is accessible to schooners at 15-feet draft."
At the time of the report, the quarry had been idle since 1914.
Granite from the quarry was used for buildings and the small sheets and waste for paving blocks. Granite from this quarry can be seen in these examples: the Milwaukee, Cleveland, Indianapolis and Jersey City post offices; the Philadelphia Mint; the Municipal Building in New York; the public library in St. Louis, Missouri, and the post office in Bangor, Maine.
