Boiling SpringsThe town of Boiling Springs, PA, has a fairly obvious name. The town was founded and named for its thirty natural springs within a 2 acre area. They release about 22 million gallons of water per day above the surface, and are the seventh largest concentration of springs in Pennsylvania. They are set apart from other springs, however, due to the underground rock formations that contribute to the unique water flow.The Boiling Springs do appear to be boiling, although they are not hot. This is due to the subterranean igneous rock that holds in the groundwater. When Pangaea broke apart, magma rushed up to fill in the faults in the upper crust. This cooled quickly, forming impenetrable sheets of basalt, or diabase dikes. Diabase dikes cut through the limestone in Pennsylvania, forming a V shape, which comes to a point at Boiling Springs. Because the water can penetrate the limestone but not the basalt, it comes to head at Boiling Springs, forcing itself to the surface, which creates the bubbling, boiling movements as it hits the air. The most famous spring in Boiling Springs is the Bubble, which is located directly behind the Boiling Springs Tavern, an 1845-built restaurant that served as a stop on the Underground Railroad. It’s a sight worth the detour. -- source link
