Some of Burroughs' essays came out of trips back to his native Catskills. In the late 1880s, in the essay "The Heart of the Southern Catskills," he chronicled an ascent of Slide Mountain, the highest peak of the Catskills range. Speaking of the view from the summit, he wrote: "The works of man dwindle, and the original features of the huge globe come out. Every single object or point is dwarfed; the valley of the Hudson is only a wrinkle in the earth's surface. You discover with a feeling of surprise that the great thing is the earth itself, which stretches away on every hand so far beyond your ken." The first sentence of this quote is now on a plaque commemorating Burroughs at the mountain's summit, on a rock outcrop known as Burroughs Ledge. Slide and neighboring Cornell and Wittenberg mountains, which he also climbed, have been collectively named the Burroughs Range.
