The top photo is of Bad Water Basin in Death Valley, CA taken from the top of Dante’s Peak.
The center photo is an “impression” of Mesquite Flat Sand Dunes.
These dunes are the best known and easiest to visit in the national park. Located in central Death Valley near Stovepipe Wells, access is from Hwy. 190 or from the unpaved Sand Dunes Road. Although the highest dune rises only about 100 feet, the dunes actually cover a vast area. This dune field includes three types of dunes: crescent, linear, and star shaped. Polygon-cracked clay of an ancient lakebed forms the floor. Mesquite trees have created large hummocks that provide stable habitats for wildlife.
(The Mesquite) … comes as near characteristic of the whole Southwest including much of Mexico, as any species of plant life known to the region. It is as native as rattlesnakes and mocking birds, as characteristic as northers, and as blended into the life of the land as cornbread and tortillas. Men and other animals were using it untold generations before Columbus sailed; they are still making use of it.
