DEATH VALLEY NATIONAL PARK, Calif. - The National Weather Service says California's Death Valley National Park tentatively recorded a high temperature of 53.8 degrees Celsius on Sunday, which would tie the all-time June record high for the United States.
The weather service's Las Vegas office on Monday posted to its website a photo of a Park Service thermometer showing the mercury on June 30.
The reading preliminarily ties the U.S. June mark of 53.8 C recorded on June 23, 1902, at Volcano, a former town near the Salton Sea in southeastern California.
The reading, however, is short of the all-time, world record 56.67 C set in Death Valley on July 10, 1913.
