Seven Tubs Nature Area is known locally as The Tubs or Whirlpool Canyon. This outstanding geological phenomenon features seven large "potholes" or "tubs" gouged out of the hard, gray sandstone of the Pocono Formation by Wheelbarrow Run.  Many geologists believe that the tubs were formed during the last Ice Age more than 10,000 years ago, when the force and volume of a rock-filled glacial melt water stream etched the seven, tub-shaped potholes and gorge into the underlying rock. The Seven Tubs Nature Area is approximately 532 acres and is located in Laurel Run Valley between Wyoming and Wilkes-Barre Mountain. It is about four miles southeast of downtown Wilkes-Barre.
