Archbald Pothole State Park is worth visiting to see the world’s largest glacial pothole. It’s 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 it could hold about 140,000 gallons. It would take 35 fire truck tankers to fill the pothole.
Regardless of its formation, this glacial pothole is a geological wonder: At 38 feet deep and 42 feet by 24 feet wide at its largest diameter, it could hold up to 140,000 gallons of liquid and would take 35 firetruck tankers to fill.
The park is 150 acres, and there is a large viewing platform overlooking the pothole.
Admission and parking are free. It’s pet friendly and has a small loop trail that follows an old coal mine tram road for hiking. The trail passes along a rock ledge and through a forest.
It’s 16 miles northwest of Lake Ariel and 6 miles southwest of Carbondale.
