Maynard Art Show: This photo of the Andes Mountains that straddle Argentina and Chile illustrates a point that artists have long known. Brown isn’t one color, it's a rich pallet, here tinted red, grey and even blue. At the highest elevations, a band of snow adds even more variety. As the astronauts fly over South America, the see the Andes as a spine of mountains along the entire Pacific Coast. They were formed over hundreds of millions of years as two massive plates of Earth’s surface collided, pushing up this mountain ridge. Active volcanoes pepper this ridge, confirming that Earth’s plate tectonics continue.
