One recent book on just that subject -the Erie Canal's affect on New York
State - is Carol Sheriff's 1996 book The Artificial River: The Erie Canal
and the Paradox of Progress.

There is a Mount Pleasant in the Adirondacks but that one, like Oswego
County is far more than 34 miles from New York City. It's either a section
of another town or perhaps Pleasantville, New York, in Westchester County,
which would be about that distance from NYC.

Good luck,
