An Astronaut's View of the Colorado Plateau
The
Colorado Plateau spans northern Arizona, southern Utah, northwestern
New Mexico, and southwestern Colorado. This physiographic province is
well known for its striking landscapes and broad vistas—an impression
that is enhanced by the view from the orbital perspective of the
International Space Station. This astronaut photograph highlights part
of the Utah-Arizona border region of the Plateau, and includes several
prominent landforms.
The Colorado River, dammed to form Lake
Powell in 1963, crosses from east to west (which is left to right here
because the astronaut was looking south; north is towards the bottom of
the image). The confluence of the Colorado and San Juan Rivers is also
visible. Sunglint—sunlight reflected off a water surface back towards
the observer—provides a silvery, mirror-like sheen to some areas of the
water surfaces.
The geologic uplift of the Colorado Plateau led
to rapid downcutting of rivers into the flat sedimentary bedrock,
leaving spectacular erosional landforms. One such feature, The Rincon,
preserves evidence of a former meander bend of the Colorado River.
