Chaffin Ranch Cold Water Geyser is another geyser created by man when drilling core samples, the same process that created the nearby Crystal Geyser. The drilling allows water to permeate a C02 laden layer of rock. Once the pressure builds up, the drill hole provides an escape for the C02 and water. After an eruption, ground water recharges the system, and the process continues.

Chaffin Geyser typically erupts every 2-4 hours, much more frequent schedule than Crystal Geyser. The geyser, however, does seem to be seasonal. It appears to be more reliable in the spring and summer, and it erupts less often in the late fall and winter. This is likely due to ground water levels. At its peak, it erupts up to about 10 m ( 33 ft. ) high. The geyser is a great place to visit with kids.

If visiting, plan on spending a few hours. If the area around the geyser is completely dry, it may be a time of year when it doesn't erupt very often. Several old abandoned cars in the area give the place added character.
