      • Diabase

The Lookout is part of a circular formation, which surrounds the Quakertown area, of diabase intrusion that occurred during the Triassic approximately 200 million years ago. A similar formation is located around the area which includes Pennsburg, East Greenville, and Red Hill, in Montgomery County, Pennsylvania. The only other known similar formation is located in South Africa. [3] The diabase is typically dark gray to black, dense, and fine grained, consisting of predominately labradorite and augite. [5]
