Hot Creek Geologic Site is located near Mammoth, Lake just off the 395 Highway in Mono County, California. The stream originates from Twin Lakes in Mammoth and continues on to Lake Crowley. The site is located near and a beautiful cold water stream which is located over a geothermal vent. Warm water is heated from a magma chamber located about three miles below the earths surface and bubbles up into the steam warming the water.
The Hot Creek does offer excellent fishing opportunities and popular among fly fisherman. Fishing used to be limited to barbless hooks.
No Swimming
The stream is now closed to swimming becuase “Earthquakes can cause sudden geyser eruptions and overnight appearances of new hot springs at Hot Creek. Water temperatures can change rapidly, and so entering the water is prohibited. ” Reports of hot water geysers up to 6 feet tall in 2006 and rapidly fluctuating temperatures apparently caused the closure of the stream to swimming.
My grandfather used to point out that some hot water vents where not in the same locations as when he was a child. Perhaps, within my life the hot springs area has become too dangerous to swim.

I recall active conversations about the possibility of an geyser eruption which would kill us and we understood the risk of swimming. However, we also understood the possibility of an such an event was very remote when one considers the geologic time tables.
