Death Valley National Park began a nine-day run of excessive heat on July 4, with the temperature hitting 125 degrees Fahrenheit or higher, the second-longest streak in history.
Signs at the California park warn visitors that “heat kills” and that rescuers may be hours away, but visitors have still been caught off guard during this month’s deadly heat wave.
A motorcyclist died from heat exposure on July 6 when the temperature soared to 128 F.
Bystanders last week carried out an unconscious woman who had gotten lost and had no cellphone service.
