Jenny Jump State Forest is located in Warren County along the stunning rolling terrain of Jenny Jump Mountain Range. Panoramic vistas of the Highlands and the Kittatinny Mountains and Valley to the west, and scenic views of the Great Meadows in the east dramatically greet the visitor who climbs the narrow path leading to the top of Jenny Jump Mountain. Rocky outcroppings and boulders line the trail - evidence that great glaciers once covered what is now known as Jenny Jump State Forest.

Jenny Jump State Forest Map


Glaciers receded from Jenny Jump Mountain near the end of the Wisconsin Ice Age, about 21,000 years ago. Exceeding a mile in thickness, the ice advanced southward from Canada, gouging out valleys and rocks from mountain tops, incorporating sediment, boulders and debris into its mass. Much of this debris was carried by the glacier or transported by meltwater to the edge of the ice where it was deposited in huge ridges called moraines. The dramatic effects of this can be seen in Jenny Jump State Forest.
