STS108-701-21

July 14, 2011
One of the STS-108 crew members used a 70mm camera to take this nearly vertical picture of part of the Galapagos Islands. Lava flows appear as dark stringy patches leading down the flanks of volcanoes which comprise the large, seahorse-shaped island of Isabela. Other flows appear on the flanks of Fernandina Island, the smaller round island to the left, which is made up of a single large volcanic cone. The Galapagos Islands, according NASA geologists studying the STS-108 collection, lie above a hot spot underneath the oceanic plate that has been active at least for tens of millions of years.
