Archbald Pothole State Park, Geological state park in Archbald, Pennsylvania, US.
The Archbald Pothole measures 38 feet deep with an elliptical shape, featuring a maximum diameter of 42 feet by 24 feet at the surface.
Coal miner Patrick Mahon discovered the pothole in 1884 while extending a mine shaft, causing water and stones to rush into the excavation site.
The pothole served as a prominent research site for geologists studying glacial formations from the Wisconsin Period, dating back 15,000 years.
The park closes annually from the third Saturday of November until the second Friday of April, with daily operations ending at sunset.
The geological formation contains a volume of 18,600 cubic feet, sufficient to hold 140,000 gallons of water or the equivalent of 35 fire truck tanks.
