”Iskilde” means ”cold spring” in Danish. The artesian spring was discovered in the Mossø Conservation area in a remote part of the Danish lake highlands in 2001 by a retired insurance broker and his wife.
The aquifer from which the spring flows lies 150 -180 ft below the surface and it is covered by alternating layers of quartz-sand and hard clay. The exact age of the water is not known, but it is believed to be rather old, possibly dating back to the latest ice-age according to a geologist familiar with the area.
With a temperature of below 8 degrees, the spring is unusually cold.
