As the Expedition 7 crew on the International Space Station was set to come home to Earth, crew member Ed Lu was inspired to photograph his hometown, Honolulu, during an overpass. Honolulu is striking for the way it is bound by surrounding geography. Built-up fingers of the city extend northeast onto the steep volcanic slopes and surround the volcanic craters of Punchbowl and Diamond Head, leaving undeveloped only parklands and the steepest ridges. They are both tuff cones that formed as magma from the erupting volcano came in contact with ground water at a time when sea levels were higher than they are now. As the water turned to steam, it caused an explosion that formed a hill of ash with a broad crater in the center.
