STS109-718-102

July 18, 2011
The astronauts on board the Space Shuttle Columbia took this 70mm picture featuring the Galapagos Islands. For orientation purposes, north is towards the bottom of the view. Most of the largest island in the Galapagos group, Isla Isabela, stretches across the middle of the frame. The circular feature on this island at bottom is Volcano Wolf (1707 meters in altitude). Volcano Darwin (1280 meters in sea level) is the next volcano above and to the left, partly ringed with cloud. The single island top right is Isla Fernandina, the top of another volcano (1547 meters). Recent lava flows appear as darker surfaces and the older surfaces appear green, as a result of unusual rains and vegetational greening in this normally arid part of the world. The Equator passes exactly through Volcano Wolf, roughly left to right.
