Bubbling Spring does as its name promises – it bubbles. In the spring pool,
the surface bubbles in many places from the spring water de-gassing. To our
knowledge the gas has not been tested but there is no odor. On Oct. 11, 2003
the flow of the spring was estimated to be 500 gallons per minute. Although
the spring rises in sandstone, it is most likely limestone waters
resurgence.

A not uncommon sight in limestone country - a little spring house with clear
sweet spring water flowing down a moss covered channel.

An abandoned spring house located in a remote mountain hollow. In earlier
years the homestead was sited near a good spring. With "county water" and
wells readily available, a weed covered foundation and the spring box may be
all that is left.

This karst spring runs milky to muddy but never runs clear - at least not in
recorded history!

Another "milky Spring" in Southwest Virginia. This cloudiness may be due to
heavy rainfall causing sediments to be carried by high flow rates.

Some springs still have ram pumps that pump without electricity. These
pumps usually require a large spring to operate effectively.

Some big karst springs are used as water supplies. This one is called
Big Spring. There are two overflow pipes for this large spring (approx. 500
gallons per minute) which is used as a public water supply for a small town.
