This is the lowest point in the North American continent, Badwater, Death Valley National Park at 282 ft (86m) below sea level. It was 104 degrees (40 C) when I took this photo. The white color is caused by people walking out to the actual low point in the middle of the valley. It is an alkali salt and the white color reflects the heat and makes it seem that much warmer. Not a pleasant place to spend a lot of time, but a unique experience.
The mountains across the valley include the highest point in Death Valley National Park … Telescope Peak at 11, 043 feet (3366 m). Quite a contrast in elevation in a short distance.
