the south by the alignment of 192nd Street. A small section at the park's southwestern corner is located between Cabrini Boulevard to the east and Henry Hudson Parkway to the west, and is bounded to the south by 190th Street. The park is adjacent to Inwood Hill Park to the north and Fort Washington Park and Riverside Park to the south; all are part of the Manhattan Waterfront Greenway. The park offers views of the Hudson River, the George Washington Bridge, and the New Jersey Palisades, to the west; Washington Heights to the south; Inwood and the Bronx to the north; and the Harlem River to the east. The north–south Henry Hudson Parkway and Amtrak's Empire Connection run alongside the western edge of the park. The park is built on a formation of Manhattan schist and contains examples of igneous intrusions and of glacial striations from the last ice age. The lower lying regions to the east and north of the park are built on Inwood marble. Outcroppings of gneiss and schist can be seen interlaid with the marble, as seen in the outcroppings at the park's edges. Fort Tryon Park also contains a large glacial pothole. The northern boundary of the park is formed by the seismologically active Dyckman Street Fault. The fault creates a valley separating Fort Tryon Park from Inwood Hill Park to the north. In precolonial times, a Native American road ran within this valley from the present-day intersection of Broadway and Dyckman Street to a settlement on the Hudson River. The valley formerly contained an inlet named Little Sand Bay, which flowed into the Hudson River to the west. As recently as 1989, activity of this fault caused a magnitude 2 earthquake. Another valley separated Fort Washington from a hill to the east, which hosted Fort George. This valley contained a stream, which was known as the Hessian Spring. The stream emptied into Half Creek (later Sherman Creek), which in turn led to the Harlem River to the east. History Site The northern portion of Manhattan was first known to be inhabited by the Wecquaesgeek tribe of Lenape Native Americans, who referred to the area around Fort Tryon Park as Chquaesgeck. When Dutch settlers inhabited the lower Hudson Valley in the early 17th century, they attempted to force the Native Americans out, and some of the Wecquaesgeeks continued to occupy the area. The tribe had
