In the April 18, 2022, Flashback Friday, the e-publication of the Historical Society of Rockland County, a photograph dated 1887 along with a newspaper reprint from 1872 depicted Sugar Loaf, a small mountain in Sparkill.  A mountain in downtown Sparkill? Named Sugar Loaf? Can this be true? If there was a Sugar Loaf Hill, what happened to it? Thanks to geology detectives Tom Perry and Karl Mattsen, both science teachers at Nyack High School, the mystery is solved. It isn’t only true, it’s an almost unbelievable story.
