 One of those visitors, Princeton geography professor Arnold Henry Guyot, spent much of his summers in the early 1870s striking out to other mountains in the region.He easily became convinced that High Peak was not, as the hoteliers claimed, "the" high peak of the Catskills.His candidates turned first to other popular local suspects such as Black Dome (known as "Black Top" at the time), then Hunter Mountain and finally to Slide Mountain, in an inland area to the southwest known at the time as the Shandaken Mountains and dismissed by the hotelkeepers as a different range entirely.
