Earth as Art: The Andes

Vivid colors belie the arid landscape of northern Chile where the Atacama Desert, one of the world’s driest, meets the foothills of the Andes. Here salt pans and gorges choked with mineral-streaked sediments give way to white-capped volcanoes.

Geo-Pict of the Day

Today’s Geo-Pict is from NASA’s Earth as Art series, a striking satellite image of Lake Disappointment in Western Australia.

Lake Disappointment is an ephemeral salt lake that covers approximately 370,650 acres on the edge of Western Australia’s Gibson Desert. Explorer Frank Hann supposedly named the lake in 1897 after following a number of creeks that he thought would lead to a large lake. They did, but the lake’s extremely salty water was not drinkable.

Extensive wetlands lie near the town of Yellowknife, near the Great Slave Lake in northern Canada. The shallow lakes seen in this image have formed in grooves in the landscape that were carved by glaciers during the last Ice Age.
