Scientists Contemplate Tilting of Rock Layers on Mars (http://www.jpl.nasa.gov/missions/mer/images.cfm?id=1620)

Scientists hope to better understand the structure of the hills and perhaps determine how they were formed by observing how the orientation of layers in these outcrops changes throughout the region. Hypotheses include that the Columbia Hills are the remains of an ancient volcano, a remnant of an old impact crater formed by an asteroid or comet, or delta deposits formed where water flowed into Gusev Crater early in its history.
