Temperatures of nearly 120 degrees Fahrenheit claimed another life at Death Valley National Park in California.
On Aug. 1, 57-year-old Peter Hayes Robino died of hyperthermia, or overheating, after driving his car off a 20-foot embankment. It is the second heat-related death in the park in recent months.
Symptoms of hyperthermia can include confusion, irritability and lack of coordination.
According to bystanders, Robino stumbled back from a trailhead and got into his car. They offered him help but he declined, though they said his responses did not make sense.
