Identification as highest Catskill peak For a mountain with so many superlatives, Slide actually took a long time to be discovered for what it was. The mountain received its name locally from a
landslide in 1819 on its north face near the summit. The scar can still be seen today, and was partially gouged out again by another slide in 1982. Slide would not be established as the highest peak in the range until 1886, long after much of the interior Northeast and their mountain ranges had been surveyed and settled. Due to land disputes and schemes that dated back to the colonial period, no complete, impartial survey of the entire Catskill region had been carried out until then. Seven years earlier,
Princeton geology professor Arnold Henry Guyot had been staying at the
Catskill Mountain House when he became interested in the surrounding mountains, and management's claim that nearby
Kaaterskill High Peak () was the highest in all the Catskills despite growing doubt. His survey, carried out on his own time and at his own expense, established that Slide, located some distance to the southwest, was far and away the highest peak in the range. His findings were vehemently disputed by the hotelkeepers around
North-South Lake until others confirmed his results. There was a movement, once its status had been confirmed, to give Slide a name believed to be more fitting for a highest peak. "Mount Lincoln," after the late U.S. president, was considered for a while. But it ended when Guyot announced that he preferred Slide, as he had followed local custom wherever possible in naming the peaks for his survey. Legends have grown up over the years in the Catskills over this belated discovery of the range's highest peak. Some tell of a new owner of
Hunter Mountain, the range's other 4,000-footer and second-highest peak, swinging a
level around to ensure he had bought the highest peak until being stopped by Slide. Another story has
John Burroughs, who later became rich and famous writing about his hikes up Slide and other nearby mountains, proving the case atop the mountain by having his friends aim a
rifle with a ball in the barrel at all other contending peaks and observing that the ball fell out every time. Regardless, tourism soon shifted to the new highest peak, and a local woodsman, Jim Dutcher, who knew the mountain well from his days peeling
hemlock bark for
tanning, built a
hotel and did a regular business escorting visitors to the summit up a trail he built in 1880. While it runs over privately owned land and has been abandoned since 1941 save for the final section leading across the summit ridge from the west, it still exists and can be followed.
Forest Preserve Around the same time, Slide would prove instrumental in creating New York's
Forest Preserve as it exists today. Some of the other private lands near the mountain had been utterly deprived of any value by tanners who had decided to boost their profits by neglecting to pay their
property taxes and simply leaving the area. At that time, when the county took possession through
foreclosure, it was among those required by the state to guarantee payment of state property taxes. Many county voters and landowners felt shafted, leading Ulster to refuse to pay despite a court order. Their representatives in
Albany worked out a compromise by which the lands in question were given to the state as part of the newly established Forest Preserve, originally meant to include just the
Adirondacks, to satisfy the county's unpaid debts to the state. That was the beginning of what ultimately became the
Catskill Park. On June 11, 1886, a delegation from the state's forest commission climbed Slide to give some sort of official recognition to the peak and the Catskill Forest Preserve. While they used Dutcher's trail, the man himself did not take part ... in fact, he did no maintenance on the trail beforehand, since he was a
Republican and the commissioners had been appointed by
Democratic governor David Hill. Nevertheless, the party got to the summit, where
Townsend Cox, head of the commission, declared the view as fine as anything to be found in the Adirondacks. The next year the state decided to use along the West Branch of the Neversink at the west slope of the mountain (south of the current trailhead) to reintroduce
white-tailed deer, which had been seriously thinned in the area over the preceding century. A wooden
fence was built around the whole area to protect them from
poaching, and eventually 95 deer were released back into the wild, successfully re-establishing the species.
Ironically, today there are actually very few deer in that area, because the undisturbed forest no longer offers as much of the second- and third-growth species deer prefer to feed on, and
predators such as
black bears have become more numerous as well. The new legislation helped Slide score a significant first in 1892, when the state appropriated $250 to build a
trail, paralleling Dutcher's, up the west side of the mountain — the first trail built at public expense in the Forest Preserve. A survey was also authorized to determine whether it was on public land, and even though it was not the trail was built anyway. While heavily
eroded and rocky, it is still in use today as part of the
Burroughs Range Trail and remains the most frequently used ascent. Two years later the Forest Preserve legislation was written into a new version of New York's constitution as Article 14.
John Burroughs near summit Slide's fame was spread far and wide by Burroughs. He had often been able to see the peak's summit ridge from
Old Clump Mountain near his boyhood home in
Delaware County, likening it to seeing a
horse grazing from behind. He tried to climb the mountain several times with friends, and his account of his successful ascent from nearby
Woodland Valley, "The Heart of the Southern Catskills," is one of his best works. He wrote of the view from the summit: :
We saw the world as the hawk or the balloonist sees it when he is three thousand feet in the air. How soft and flowing all the outlines of the hills and mountains beneath us looked! The forests dropped down and undulated away over them, covering them like a carpet ... :'' All was mountain and forest on every hand. Civilization seemed to have done little more than to have scratched this rough, shaggy surface of the earth here and there. In any such view, the wild, the aboriginal, the geographical greatly predominate. 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.'' "Here the works of man dwindle," was put on a
plaque near the summit by the
Winnisook Club shortly after his death in 1921 and placed on a ledge near the summit that offers the best view from the mountain. It has since been known as Burroughs Ledge.
Eugene Bicknell Another early visitor to the mountain was an amateur
ornithologist from
Brooklyn named Eugene Bicknell. On one of those days, he caught a small brown
thrush near the summit which he was unable to identify as belonging to any known species of that time. The bird was named Slide Mountain thrush at first, then
Bicknell's thrush when it was found living high up in the
boreal forests of other Northeastern mountains. But it was not studied, as prevailing scientific opinion of the time considered it a subspecies of the
gray-cheeked thrush. Only in the late 20th century did newer research methods such as
DNA comparisons prove that it was, indeed, a separate species, setting off a scramble to save
habitat and learn as much as possible about it.
Early 20th century The trail built in 1892 had been meant to facilitate travel to the lookout towers that existed in some form or another on the mountain's summit. Recreational visitors found views from the summit severely limited without a stand to get above the trees; the state was interested in fire control. Despite the peak's importance in establishing the Forest Preserve in the Catskills, much of the land remained in private hands. While purchases in 1900 did much to change that, it would take until 1928 before the state actually acquired the summit property and much of the land it had already built a trail on. During
World War II, a small military training plane crashed on the mountain's east slope at about . While most of the debris is gone, the site can still be reached via a short side path from the Burroughs Range Trail.
Fire lookout tower The first fire lookout structure built on the mountain was a wooden tower. The site was operational in 1912, at which time the site was deemed unsuitable for fire lookout operations and later officially closed in 1916. In 1934, a steel tower was built on the mountain, but was never used for fire lookout purposes. The tower later deteriorated and was removed in 1968.
Wilderness area In the mid-1960s, the formal organization of the
Catskill Mountain 3500 Club, the range's first
peak bagging organization, gave more hikers a reason to climb the mountain as they were required to do so at least twice, once in wintertime and once during the rest of the year, for membership. Around the same time, the
Long Path was also routed over the mountain when it was finally established as a marked trail rather than a collection of points of interest. The summit is still the highest point on the entire trail. A major change in management of the mountain occurred in the mid-1970s, after the state's Conservation Commission had become the Department of Environmental Conservation and the Temporary Commission on the Future of the Catskills had recommended that it establish a master plan for all the Catskill lands. Slide would wind up lending its name to the state-designated
Slide Mountain Wilderness Area, the largest in the Catskills at . New regulations also ended abuse of the summit by campers. For many years, the first or so of the trail climbing Slide crossed the property of the nearby
Winnisook Club. There was a metal gate across the Burroughs Range Trail marking the property line, below which nearly every tree had a No Trespassing sign on it. Because of the 1970s hiking boom, parking along the road at Winnisook Lake (there was no parking lot) had become a nightmare. In the late 1970s, the
New York State Department of Environmental Conservation solved the problem by buying the land south of the ridgeline from the
Winnisook Club, making all but the last stretch of trail to Winnisook Lake public land. Then, in its first-ever Unit Management Plan for the wilderness area, they built a new
parking lot further south down Ulster County Road 47 and relocated the trail onto the new public land, ending at the new parking lot. This was the trailhead for a new section of the
Phoenicia-East Branch Trail, which connected to the carriage road commonly used very near the base of the Burroughs Range Trail. This new section requires crossing the west branch of the Neversink right at the beginning. While it is normally not difficult to follow the stepping stones, the creek can be impassable and even fatal in high water. In December 2000, Timothy O'Lear, a
Boy Scout from
Long Island drowned when he fell in and was caught under some nearby tree branches when returning after a weekend
backpacking trip. He is memorialized with a small plaque on a bench at the beginning of the trail. In 2023 a family from New Jersey was ticketed by a DEC forest ranger after they brought several homemade
Adirondack chairs to the summit, assembled and left them there, with the intent that people could sit on them and enjoy the views. They were told by two volunteers from the 3500 Club that doing so was illegal under state regulations governing wilderness areas. A DEC forest ranger met them on their descent and told them to return to the summit and remove the chairs. After they refused to do so, they were issued a ticket carrying a fine as high as $325. The ranger and another volunteer removed the chairs. ==Natural environment==
