Archbald Pothole..

Archbald Pothole State Park

State park is open as of June 2018, well marked on Business Route 6 just past the Jeep dealership. Informational signs describe how the pothole was formed and how it was discovered. Impressive natural wonder! Well worth a quick stop on your personal "World's Largest" tour.

The proud on-site signs proclaim this to be a "world-class" pothole. Discovered in 1884, it's 38 feet deep and could hold enough water to fill 35 fire trucks.

Despite it being closed, this is a 1 minute walk off Rt 6. To quote my 8 year old son: "I'm actually impressed." Worth a detour if you're near Scranton or passing through.

Pretty little park, but idiots have thrown some trash in the hole. Easy, quick visit. No facilities, no explanatory plaque or display. Nothing else to see there but the pot hole. Still, glad we went. A nice little break from driving.

Lovely little park located right off busy highway. As a friend told me when I said where I was going, "It's a really big hole!"

Archbald Pothole.

Archbald Pothole State Park

Things seem to be good here at the Archbald Pothole. I took this photo on a road trip with my niece. I grew up near the Pothole -- now I live in New Jersey. As far as the State Park, there isn't any information posted... Just the sign on the road. Then you pull into the parking lot, and look into the pothole. There are no signs explaining anything. The photo shows a platform that you walk up onto to look down into the hole.
