The bluish shimmering lemon water, which presses to the surface, appears to be clean, but like most karst springs in the Swabian Alb, it is heavily contaminated with nitrate, germs and other inputs from agriculture. Some trout used by fishermen frolic in it. The Haldenstein Cave, about 100 meters away, has signs of a forerunner of the Lone Spring.
