Joppenbergh Mountain, a prominent limestone and dolomite ridge in Rosendale, New York, helped shape the area’s karst landscape and became an important source of stone for Rosendale natural cement after extensive deposits were identified in 1825. Heavy quarrying by cement companies left the mountain dangerously weakened, leading to dramatic collapses in 1899 that damaged the canal and nearby road, though all 150 miners escaped harm. Later, Joppenbergh became known for ski jumping, hosting competitions from 1937 into the early 1970s, including appearances by Olympic skiers. In the twenty-first century, it remained central to local debate until the Open Space Institute purchased the property in 2011.
