Mount Hope Cemetery is a collection of hills and glens left behind by the last ice sheets that once covered the area. But there is more to the geological make-up of the Cemetery than just holes and hills: the stone used to make the markers and monuments tell their own tale about New York State going back more than 400 million years.
