What is the hottest place in the United States?

The hottest air temperature ever reliably recorded in a desert was 134 degrees F in Death Valley of the Mojave Desert in California on July 10, 1913. An even warmer temperature of 136 degrees was recorded a few years later in Libya but that has been discounted as inaccurate as it was not properly measured by untrained Italian soldiers. A recent ground temperature was measured by a satellite in Iran that was even hotter but the ground temperature does not reflect the temperature of the air above it. Anyone who has walked barefoot over an asphalt parking lot in summer can attest to that.
