Now part of the Palisades Interstate Park Commission, the area was saved in the early 1900s as development along the river began to destroy much of the area's natural beauty. Many efforts were made to preserve the area. Led by Union Pacific railroad president E.W. Harriman, a group of wealthy and influential businessman donated land as well as large sums of money for the purchase of other properties in the area.

Unformatted text preview: intrusion and minor faulting, the area remained fairly quiet until it was glaciated during the last ice age which ended about 12,000 years ago. Active research projects are further refining this history. There are folds in rock strata, faults that formed under a variety of conditions, intrusions of magma. The glacial features include glacial erratic, polished rock surfaces, ice striations, pot holes, a glacial delta and even the fjord of the Hudson River. This is one of the trails of Bear Mountain. These trails give panoramic views of the area. Lately there has been a concerted effort to preserve the Highlands on the private, state and federal level primarily to protect our water resources. The science behind the industrial development and environmental issues can be shown in rock exposures along the trails thus benefiting hikers, just like me!...
