Although it is less than 150 acres in size, Archbald Pothole State Park is one of the most intriguing public recreational spaces in the Pennsylvania state park system.

Located at an elevation of 1,211 feet, in the northeastern part of the Keystone State, its main drawcard is the fascinating Archbald Pothole.

An enchanting, natural geologic feature that was formed around 15,000 years ago, during the Wisconsin Glacial Period. Which has been attracting interested visitors ever since it was discovered in 1884.

As well as this main focal point, the park also has a nice walking trail and is a popular spot for hiking and birding.

There is no accommodation onsite, although plenty of campgrounds reside within 30 miles of it, while the historic town of Scranton is just a 20 minute drive away.

About the pothole

The pothole was discovered by a coal miner called Patrick Mahon, whilst extending a mine shaft.

Elliptical in shape, the pothole is believed to be the biggest in the world.

About 38 feet deep, its diameter is 42 feet by 42 feet at its largest point, although it does narrow the further down it goes, to a minimum of 17 feet by 14 feet at the bottom .

Overall the pothole has a volume of around 18,600 cubic feet and could hold some 140,000 gallons of water. To fill it up, it would take 35 fire truck tankers to do so.

Cutting through layers of shale, coal and sandstone, the pothole was formed as a result of glacial meltwater.

Seasons and Hours

The park is open from the second Friday or April to the third Saturday of November.

Its day use areas open from dawn and close at dusk.
