With regard to question a number of pages back about underground railroad -- YES -- Franklin County and the north country in general were part of the underground railroad back in the early/mid 1800's -- helping slaves escape to Canada.
"The Rev. Ashbel Parmelee was the leading abolitionist in Malone. He was the pastor of the First Congregational Church, a documented site on the New York Underground Railroad Heritage Trail, where anti-slavery meetings were held and where it is believed fugitive slaves were secreted in the basement."

Jabez Parkhurst, who lived in Franklin County next to Clinton, in the small village of Fort Covington, only a half-mile from the Canadian border, was known to have aided fugitive slaves. His involvement is reported in Frederick Seavers Historical Sketches of Franklin County published in 1918, which cited several sources. One of them, Marshall Conant, was an ancestor of a Dr. Conant, an officer in the Eastern New York Anti-Slavery Society. He reported that, Mr. Parkhurst was an ardent abolitionist, and many a runaway was harbored and fed at his home. http://undergroundrailroadconductor.com/New_York.htm

I think the "tunnels" were more hiding places though -- not actual transport ways
