Death Valley National Park
The hottest and driest of the national parks in the USA
Death Valley has a subtropical, hot desert climate, with long, extremely hot summers and short, warm or mild winters as well as little rainfall. As a general rule, lower altitudes tend to have higher temperatures.
The valley is surrounded by mountains, while its surface is mostly flat and devoid of plants, and so much of the sun's heat can reach the ground, absorbed by soil and rock. Death Valley holds temperature records because it has an unusually high number of factors that lead to high atmospheric temperatures.
