As one of the earliest patented businesses (1600's for grinding bark
for tanning hides in the vicinity of Wall Street) in New Amsterdam/New
York you would perhaps think there are many examples of leather from
it. I'm not sure if there has been many. One place, Bestevaers
Cripplebush, a swamp never deeded by the Dutch government to anyone,
on the edge of which was hung one Jacob Leisler, exonerated under
William and Mary (there was no water in the fort, nor people when the
British Navy showed up and well William was of Orange and Mary of
England anyway), became the tannery vats of the Roosevelt's (the
former President Franklin Delano Roosevelt side, the former President
Theodore Roosevelt side's father was a mere glass importer) and about
it is said in business history, more money made in the preparation and
tanning of leather than any other business until the modern era. As
health concerns arose, primarily from flies and hide preparation, the
industry was moved in stages to the periphery of settlement,
especially after mid-nineteenth century studies by citizens, not city
agencies, brought wide-scale suggestions from study and improvements
to public health on Manhattan island.

Some of the few shoe examples I've seen from archaeological contexts
were made with many rosewood pegs instead of brads or nails, made to
fit as it were to specific customer, and an itinerant travelling class
of cobblers (some say leprechauns, often depicted as cobblers)
travelled into the countryside often to visit a farm or farmstead once
a year to shod the families and workers there.

One of the last hide processing places I'd discovered recently, began
in the 1850's in North Creek, NY where great stands of hemlock trees
were cut, their bark used to tan the hides, many more later brought in
by train, as many as 10,000 a year, until the 1880's. Later in the
19th century garnet mines (the state gemstone, the scallop the state
shell) were exploited nearby next to where in the 1930's skiing begun,
inspired by Lake Placid's Winter Olympics, and people were brought
from NYC and elsewhere by train, which became today nearby Gore
Mountain for skiing, with better than an old V8 car as a ski rope
lift. There's an interesting history of shoe leather!

Further north, titanium was mined  in the 1940's and 1950's near the
older abandoned McIntyre Iron Mine site, near the village of
Adirondac, recently granted money for historic preservation and
interpretation to bring the now uninhabited titaniferous iron oxide
mining location, first shown to prospectors as a solid iron dam "au
natural" by a "St. Joseph Indian" there in the foothills of Mt. Marcy,
New York States tallest mountain.

The tannery vat complex in early 18th century New York was not far
from the current City Hall, between it and the former shoreline at
Pearl Street and serviced by the James Roosevelt wharf.
