In a photograph taken from the space shuttle Columbia that’s astonishing for its clarity and breathtaking beauty, Chile and the Andes mountains look close enough to touch, while the perfect blue curve of the Earth’s atmosphere against the black void of space looks at once incredibly fragile and eternal.

Rocky Mountain National Park in Colorado contains many U-shaped glacial valleys, each of which ends at bowl-shaped region called a cirque. Cirques are the locations where glaciers accumulate most of their snow and ice, and so are the starting points for most glacial ice. Glacial erosion tends to create steep headwalls that frame in the cirque. The photo above shows the upper reaches of Glacier Gorge, which contains two cirques that merge downwards into one. The small peak (Spearhead) near the center of the photo forms a feature called an arete, as it separates the smaller cirques. (…) In the lower left corner, a hiker is perched on an outcrop of Proterozoic granite, directly in front of Longs Peak. Photo taken July 16, 2011. Credit: Marli Bryant Miller. (via EPOD)
