EPOD - a service of USRA

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
relevant links.

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.
