World's Largest Glacial Pothole!: Archbald, Pennsylvania

Archbald Pothole State Park is a 149-acre state park in Archbald, Pennsylvania.
This glacial pothole is a geological wonder: At 38 feet deep and 42 feet by 24 feet wide at its largest diameter it is the largest glacier-formed pothole on the planet. It could hold up to 140,000 gallons of liquid and would take 35 firetruck tankers to fill to the top. It has drawn tourists since just after it was discovered in 1884. The pothole is a renowned tourist attraction. Archbald Pothole was turned over to public ownership in 1914, when the widow of Colonel Hackley deeded 1-acre surrounding the pothole to the Lackawanna Historical Society. Archbald Pothole was a county park until 1961 when the property was transferred to the Commonwealth of Pennsylvania. Archbald Pothole State Park was formally opened in 1964.
