Things To Do



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. Archbald Pothole was discovered in 1884 by coal miner Patrick Mahon while extending a mine shaft. Mr. Mahon fired a blast of explosives and water and stones came rushing out. The miners fled fearing that the mountain was falling on them. Edward Jones, the manager of the mining company, investigated and ordered the area cleared of debris. About 800 to 1,000 tons of small rounded stones were removed and Mr. Jones realized that the vertical tunnel was a large pothole.
