Death Valley California. With temperatures that go well above 100 degrees F in the summer (I believe as high as 135 degrees!). This was in January and I remember laying on the dune basking in the sun without a shirt. I can only imagine what the summer is like! Death valley has one of the lowest points in the Western Hemisphere at Badwater, 282 feet below sea level With names like the Funeral Mountains, Coffin Peak, Hell's Gate, Starvation Canyon and Dead Man Pass - you can imagine that it can be quite inhospitable at times.
