Marion Steam Shovel
Also known as: LeRoy Steam Shovel

Why it's listed
A 105-ton steam shovel about the size of a railroad boxcar sits beside Gulf Road east of LeRoy, New York, near the limestone quarry where it once worked. It is believed to be a Marion Model 91, built of riveted sheet iron and cast iron with three steam engines and a coal-fired boiler. It first ran on railroad wheels; these were replaced with crawler tracks in 1923 or 1924. The shovel is considered important as a rare survivor of the machinery that made crushed stone for railroad beds and early roads. It is the only known surviving Model 91, the type used to dig the Panama Canal, and oral history suggests it may have come from that project in 1911, though no written records confirm this. It also reflects LeRoy's quarrying history and the General Crushed Stone Company, which operated the local quarry. The Town of LeRoy now owns it, and it is no longer in use.
Significance in brief: The nomination argues the shovel is a rare survivor of the technology that supplied crushed stone for railroads and roads. It is believed to be the only surviving Marion Model 91, the model used on the Panama Canal. It is also tied to the LeRoy limestone industry and the General Crushed Stone Company.
