High Plateau Section showing geology and shaded relief

 

The High Plateau Section consists of broad, rounded to flat uplands cut by deep angular valleys. The uplands are underlain by flat-lying sandstones and conglomerates. Local relief between valley bottoms and adjacent uplands can be as much as 1,000 feet, but is generally in the area of half that amount. Elevations in the Section range from 980 to 2,360 feet. Drainage of the area has a dendritic pattern. The western boundary of the Section is the Late Wisconsinan glacial border. The area between this border and the Allegheny River a few miles to the east was glaciated by pre-Wisconsinan glaciers. A large part of the Section is covered by trees of the Allegheny National Forest. There are a number of Federal Recreation Areas within the forest, mainly associated with Allegheny Reservoir.

The Section occurs in northwestern Pennsylvania and includes all of Forest County, most of Venango, Warren, and Elk Counties, and small parts of McKean, Jefferson, and Clarion Counties. There are many routes along which the Section can be viewed: US Route 6 from Smethport to Warren; US Route 219 from Ridgway to Bradford; US Route 62 from Franklin toWarren; Pennsylvania Routes 321 and 6 in McKean County, 666 and 948 in Warren, Forest, and Elk Counties, 949 in Elk and Jefferson Counties, and 8, and 27 in Venango County.
