Mined in the late 19th century of limestone as a part of the then-booming Rosendale cement industry, it also was the site of several long-distance ski-jumping competitions in the mid-20th century. At over 500 feet, and supporting the northern end of the Rosendale Trestle, it dominates the natural landscape of the Town of Rosendale. Since 1971, the majority of Joppenbergh Mountain has been uncultivated, privately owned open space, resulting in the re-growth of important habitats.
2011: The Open Space Institute (OSI) purchased the property from the Joppenbergh Mountain Corporation in July of 2011 with the WVLT and the Shawangunk Conservancy.
Today: The WVLT owns and manages the property. Parking to access the trails up the mountain is at Willow Kiln Park.
