The mercury rocketed to 128 degrees Sunday in Death Valley National Park, the National Weather Service said, tying the record for the hottest June day anywhere in the country.
But the Los Angeles Times reported that the National Park Service thermometer — 200 yards away — recorded a temperature of 129.9, which shatters the record for June.
In Las Vegas, the temperature shot up to 117 degrees to tie the city's record high and to cause more discomfort for residents and tourists in the sprawling desert city.
Since recordkeeping began in Las Vegas in 1937, the only other times the temperature reached 117 degrees were on July 19, 2005, and July 24, 1942, according to the National Weather Service.
