I asked The Soapbox Collector to take this picture to show you that a lot of the rocks in this region are coal. People still burn these rocks in special stoves to heat their houses (although the B&B has oil heat and radiators, like most people here). Power plants burn them to release energy that they turn into electricity. Mining, transporting, and burning the coal is a pretty dirty way to get energy compared to some of the ways we have available now, but a long time ago it was the best way people had to industrialize things quickly. (Kiki's saying something about whether that was necessary, but I'll ask her about it later. I know the family who runs the B&B likes the wind farm up on the ridge top better than the coal furnaces, though.)
I didn't take this picture. The State Park people made it to show how Archbald Pothole formed--somewhere between 30,000 and 11,000 years ago! The swirling water in the bottom scoured the ground with rocks, gravel, and sand, digging the pothole. You can read all about it by clicking this link: posted by Kiki Kangaroo @ 12:29 PM 0 comments
After the RailTrail, we went to Archbald Pothole. This shows me at the Pothole. Here's some of what the state park people say about this feature: "Archbald Pothole State Park is a 150-acre park in northeastern Pennsylvania. The park is named for Archbald Pothole, a geologic feature that formed during the Wisconsin Glacial Period, around 15,000 years ago. The pothole is 38 feet deep and has an elliptical shape. The diameter of the pothole decreases downward. The largest diameter is 42 feet by 24 feet. At the bottom it is 17 feet by 14 feet. The pothole has a volume of about 18,600 cubic feet, so could hold about 140,000 gallons. It would take 35 fire truck tankers to fill the pothole. "
