A vertical shaft of ascending water that does not rise to the surface of the earth but disperses through several horizontal fissures which can be at various depths. Dowsers identify blind springs as several underground streams radiating from a central point. Some of these may subdivide into smaller streams.
Blind springs are found under many ancient sites and churches but are also to be found elsewhere throughout the countryside. There is an associated energy field that is unique to a blind spring as well as
the water component. The Blind Spring will have a feeder stream at a greater depth. It is thought that the water is forced to rise up the vertical fissure due to a narrowing of the feeder stream.
Often referred to as a Water Dome in North America.
