Eynon, Pennsylvania: World's Largest Glacial Pothole

A big Ice Age hole in the ground is best seen from the specially built viewing platform.

World's Largest Glacial Pothole

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 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.

World's Largest Glacial Pothole

Near Carbondale, on Route 6, outside the small town of Archbald (pronounced "arch-a-bald") is the "World's Largest Glacial Pothole."

It consists of a hole in the ground, about 40 feet in diameter or so. It was caused by the swirling of the receding glacial waters during the last ice age. There is a concrete platform around the hole, a plaque from the Pennsylvania Historical Society, and that's about it.

When I was a kid growing up in Carbondale, it was considered an interesting thing to do, to go look at the pothole. You would drive out there, look at the hole, and say something like, "It sure is a big one" This was our bit of local civic pride.
