"The world’s largest pothole also happens to be the most popular pothole in Pennsylvania," the Only In Your States reports.

"Formed more than 20,000 years ago during the Wisconsin Glacial Period, Archbald Pothole boasts a depth of 38 feet and, at its widest point, is 42 feet by 24 feet.The pothole could conceivably hold an estimated 140,000 gallons of water."

"Discovered in the 1880s when miners were blasting to extend a mine, Archbald Pothole was originally used to help ventilate the mine. But, within time, the landowner Colonel Hackley erected a protective wall and a fence around the hole.

"Archbald Park became a huge tourist attraction, earning prestige as the world's largest pothole in what became Archbald Pothole State Park in 1964."

Archbald Pothole State Park is a 149.16-acre (60.36 ha) Pennsylvania state park in Archbald, Lackawanna County, Pennsylvania.

The focal point of the park is Archbald Pothole. The pothole is a remnant of the Wisconsin Glacial Period, 38 feet (11.6 m) deep with a largest diameter of 42 feet (12.8 m) by 24 feet (7.3 m). It has drawn tourists since just after it was discovered in 1884. Archbald Pothole State Park is on U.S. Route 6 Business in the borough of Archbald.

A small loop trail follows an old coal mine tram road for hiking. The trail passes along a rock ledge and through a forest.

Hunting is permitted on over 100 acres (40 ha) of the park. The most common game species are squirrels, turkeys and white-tailed deer. The hunting of groundhogs is not permitted. Hunters are expected to follow the rules and regulations of the Pennsylvania State Game Commission.

Testimonials from Trip Advisor:

"The park service has done a terrific job of getting you access to the pothole and it's surrounded by a fence and walkway, and even has a concrete deck on one side, allowing you to peer directly into the throat of the pothole which is about 40 feet to the bottom."

"If you are in the area, go ahead and stop. You can at least say you have been there. The parking lot is close by and there are walking trails with no signs."

"This is a quick short stop not much to look at. The story is interesting. The pothole is right beside the parking lot so not much walking. The plus is there's no charge so go check it out."
