Along with Kaaterskill Clove on the other side of Kaaterskill High Peak, it is one of only two breaks in the Catskill Escarpment. It was created during the last Ice Age as meltwater eroded its way through from the Catskill Plateau to the Hudson below. The stream that evolved is today Plattekill Creek.
In the early 19th century, early American artists were struck by the rugged, wild scenery of the clove and other locations in the northeastern Catskills. Depictions of this wilderness by Thomas Cole and others led to the artists being dubbed the Hudson River School.
A narrow, two-lane road that climbs 1,200 vertical feet (366 m) in 1.4 miles (2.2 km) from West Saugerties along the clove's north wall is the only route through it. Trucks and buses are banned from it, and it is not maintained or even plowed between November and April. The Tour de Trump bicycle race was routed through here, and the road proved so steep that even some of the top bicyclists in the world had to get off and walk their bikes (it was raining that day).
The cliffs near the clove's headwall offer spectacular views of the nearby waterfalls but have also been the site of fatal accidents. In 2010, a man from the Albany suburb of Delmar lost his footing near one and fell 100 ft (30 m) to his death. On June 4 of the same year, Olivia Rose Belfiglio fell 100 feet from the top of a cliff and died at the bottom.
