In places its continuity is broken by wind gaps, such as Culvers Gap, and water gaps, such as Delaware Water Gap. The High Point Monument, which lies at the north end of the park on the summit of Kittatinny Mountain, marks the highest point in New Jersey at 1803 feet above sea level. Kittatinny Valley lies east of the park and it in turn is bordered on its eastern side by a rugged upland called the New Jersey Highlands. Wallpack Valley, Wallpack Ridge, Minisink Valley, and the Pocono Plateau are found to the west. Shale, siltstone, sandstone, quartzite, and conglomerate form the bedrock formations in High Point State Park. These sedimentary rocks are 460 to 400 million years old, and consist of material originally eroded from ancient lands and deposited as sediment in streams and seas that once covered the area. These loose materials were subsequently buried by younger sediments, and over millions of years they eventually changed to solid rock. Repeated uplift and subsequent erosion has exposed these rocks. The strong northeast-trending ridge-and-valley topography in the High Point area developed slowly, largely controlled by the structure of the underlying rocks and their varying resistance to erosion.
