The History of the World's Tallest Thermometer


It weighs 76,812 pounds and is held together by 125 cubic yards of concrete. It stands 134 feet tall and it is capable of displaying a maximum temperature of 134, which commemorates the WORLD’S HOTTEST DAY! The record temperature 134 degrees Fahrenheit (56.67 degrees Celsius) recorded in nearby Death Valley on July 10, 1913.

It was built in 1991 by the Young Electric Sign Company of Salt Lake City, Utah; for Willis Herron, a local businessman who spent $750,000 to build the thermometer next to his Bun Boy restaurant. After its completion, and before it was ever officially lit, high winds blew the thermometer over. It was rebuilt following its collapse to be even stronger and resistant to the high winds. It was completed in October of 1992 and it has been standing ever since.


Herron sold the attraction and restaurant to another local businessman, who sold it again. After changing hands several times, the thermometer was not being maintained and in September 2012 the thermometer was turned off! The owner at that time, said that the power bill for its operation had reached $8,000 per month and that he turned it off due to the poor economy.

After being turned off the thermometer became in total disrepair and there was talk of tearing it down, which devastated Willis Herron’s Widow Barbara and his family. Barbara Herron vowed if she could ever get the thermometer back she would pay to restore it.

The family of Willis Herron recovered ownership of the property in March 2014 and Barbara Herron used her savings to bring it back to its glory! The family worked with YESCO sign company restoring the thermometer, this was dubbed, “The Big Fix”.

The “Big Fix” was completed and the thermometer was relit four months later, on July 10, 2014. The 101st anniversary of the world’s hottest day!
