The Earth Science Picture of the Day (EPOD) highlights the diverse processes
and phenomena which shape our planet and our lives. EPOD will collect and
archive photos, imagery, graphics, and artwork with short explanatory
captions and links exemplifying features within the Earth system. The
community is invited to contribute digital imagery, short captions and

   The panorama above shows  Upheaval Dome in  Canyonlands National
   Park,  Utah as viewed from the  Overlook Trail. Upheaval Dome is
   an odd appearing structure in an area of otherwise flat-lying
    sedimentary rocks. While originally believed to be a deeply eroded
   uplift dome from the intrusion of a  salt diapir (salt dome),
   evidence now indicates its origin as an ancient  meteorite impact
   structure.

   The lighter color rock at center is the  Permian  White Rim
   Sandstone of the  Cutler Group, the prominent cliff faces
   are resistant  Jurassic Wingate Sandstone, and in between lie the
   more easily eroded  Triassic  Moenkopi and  Chinle Formations.
   Evidence suggesting that this is an impact structure include the
   orientation of the  folds and  faults surrounding the structure,
   the finding of  shocked quartz in the vicinity, and  seismic
   reflection data indicating fractured rock below the structure and the
   absence of a salt dome. Photo taken on June 7, 2010.

   Photo details: Panasonic Lumix DMC-FZ50 camera; 35-400 mm zoom lens
   (f/2.8-3.7); automatic exposure; panorama created from seven images
   stitched together with Hugin 2011.0.0  Panoramic Photo Stitcher.
