It was built in 1991 by the Young Electric Sign Company of
Salt Lake City, Utah In 2013, the thermometer and accompanying empty gift shop were listed for sale. The family of Willis Herron (who died in 2007) recovered ownership of the property in 2014 and stated their intention to make it operational again. The renovation was funded with
sweat equity and a contribution from the owner's mother of US$150,000 (). The official re-lighting took place on July 10, 2014. In December 2016,
EVgo announced building the first US fast charge station for
electric vehicles at up to 350 kW. The station is located in the rear parking area behind the thermometer, visible to travelers on Interstate 15. ==References==
