Some tourists have been braving the extreme heat of Death Valley National Park in California over the last few days to snap photos of themselves by thermometers. Others have gone walking, even jogging, in the searing heat.

As a heat wave continues to bake much of the West, Death Valley tentatively recorded a temperature of 129 Sunday which would be the highest ever recorded in June in the United States.

The park has issued an alert warning visitors of the heat danger. On its website (, park authorities recommend:

Drink plenty of water: Drink at least one gallon (4 liters) of water per day to replace loss from sweat, more if you are active. Fluid and electrolyte levels must be balanced, so have salty foods or “sports drinks” too.

void hiking in the heat: Do not hike in the low elevations when temperatures are hot. The mountains are cooler in summer…

Travel prepared to survive: Stay on paved roads in summer. If your car breaks down, stay with it until help comes. Carry extra drinking water in your car in case of emergency.

Watch for signs of trouble: If you feel dizzy, nauseous, or a headache, get out of the sun immediately and drink water or sports drinks. Dampen clothing to lower body temperature. Be alert for symptoms in others.”
