Some parts of the Earth are camera shy. Cloud cover seems to be ever-present around the equator and at high latitudes—where warm water and air from middle latitudes meet cooler air and water masses from the Arctic, creating near-constant fog, mist, and marine clouds. Umnak Island is one of those spots that hides from satellite lenses.

On May 3, 2014, the Operational Land Imager (OLI) on Landsat 8 acquired this natural-color image of Umnak Island and its volcanic neighbors in the Aleutian Island chain. Part of the Fox Islands, Umnak is the third largest in the Aleutian chain and lies just southwest of Unalaska.
