The Pocono Mountains dominate this rocky and mountainous landscape with the Endless Mountains to the north and west and Blue Mountain framing the south. The Delaware River is the region’s eastern border. The Upper Delaware River Watershed, including the Pocono Mountains, is one of the most important eagle hotspots in the Northeastern United States, especially in winter.
Glaciers played a significant role in forming the northeastern counties. As the ice retreated, numerous lakes and wetlands were created. This region has more lakes than any other in the state. Swamps, bogs and lakes dot the landscape. These wet areas are surrounded by damp northern hardwood forests.
Cool mountain streams flow gently through some areas while rushing water cuts through steep ravines in places.
