DescriptionHalfway Run Natural Area (8654385532).jpg
Bald Eagle State Forest, Union County.
The natural area protects 400-plus acres of land along Halfway Run, a small, fast-flowing stream in a heavily forested mountain valley east of R.B. Winter State Park. Near the stream are many pingo scars—water-filled depressions, or ponds, that formed during the last ice age when subsurface ice rose up through the permafrost and melted as the climate warmed.
Muck has accumulated deeply in several larger scars, forming bogs overlain with sphagnum moss and hummocks, or islands, of trees and wetland vegetation.
