Badwater Basin is the lowest point in North America. The valley is a deep, narrow trough walled in by mountains: hot air sinks into it, and it has nowhere to go.

Could you survive
Death Valley?
July. 11 a.m. Your car will not move. No signal. Make four choices and watch, hour by hour, what this valley does to you.
134°F
July 10, 1913 · Furnace Creek
The hottest air temperature ever recorded on Earth. In summer, the ground itself can get far hotter than the air.
July 1996
A family of four drove into the valley in a rented minivan. Their van was found three months later, with three flat tires and nobody inside.

What would have changed everything
One button.
No signal needed.
The family from 1996 had no way to call for help, and nobody knew their route. Today, a device that fits in a pocket sends an SOS by satellite from places where your phone shows no bars at all.
- Carry at least a gallon of water per person, per day.
- Tell someone your route and when you will be back.
- If your car breaks down, stay with it.

How this test works, and its sources
- A simplified model for storytelling, not medical or survival advice. Follow the National Park Service's guidance.
- Walking in the desert sun: about 1.2 L of sweat per hour; resting at 120°F: about 0.42 L per hour (studies cited with E. F. Adolph, Physiology of Man in the Desert, 1947). Staying in the car's shade uses the resting rate.
- Thirst starts near 2 % of body weight lost; around 10 % dehydration becomes life threatening (Adolph, as cited).
- Rescue: with an SOS device, about 2 hours (an NPS helicopter took about an hour to arrive in a 2016 case, plus time to locate). If someone knows your route, the alarm comes at the missed check-in, assumed the next morning, and a car is easy to spot from the air. A person on foot is much harder to find (NPS).
