EVER CHANGING WORLD I DESERT VOLCANO

The El Pinacate craters have their origin in a volcanic shield which is located in the Mexican part of the Sonora Desert. These volcanoes have erupted for about 4 million years with the last eruption 11 thousand years ago. The age difference between the volcano domes is visible through erosion as older craters are slowly collapsing. Moving sand dunes are reclaiming the desert volcanos over time. Thus, a small circle of desert sand is gathering inside of the craters which creates the illusion of pupils. The volcanic origin of these craters brought different kinds of minerals to the surface which is the reason for the color variety from uncoloured blacks to reds and purple hues. To get an idea of the size of what you can see there is a dirt road on the right side of the third photograph.
