Piedmont Lowland Section
The Piedmont Lowland Section consists of broad, moderately dissected valleys separated by broad low hills. The Section is developed primarily on limestone and dolomite rock. Karst topography is common. Local relief in the Section is generally less than 100 feet, but may be as much as 300 feet. Elevations in the Section range from 60 feet to 700 feet. Drainage is basically dendritic in pattern, but some areas have virtually no pattern because of the well developed subsurface drainage.
The Section occurs mainly in Lancaster County, but parts of it are also in Adams, York, Berks, Chester, and Montgomery Counties. The Section can be viewed along many roads. Recommended routes are: US Route 30 from Thomasville (west of York) to Gap and also farther east in the Downingtown area; Pennsylvania Route 23 from Lancaster to Morgantown; Pennsylvania Route 340 from Lancaster to Compass; and US Route 322 from Brickerville to Beartown.
Outstanding Scenic Geologic Features in the Section include: Donegal Spring, Fruitville Quarry Fossil Site, Getz Farm Fossil Locality, Indian rock, Lititz Springs, and Rheems Quarry.
There are no State Parks or State Forest Natural Areas or Picnic Areas in the Section.
