Roan Cliffs, Utah

Utah?s Green River cuts across the Tavaputs Plateau (top) before entering
rugged Desolation Canyon (center), which cuts southward through first the
Roan and then the Book Cliffs ? two long, staircase-like escarpments that
run west-east from Utah into Colorado. Desolation Canyon, seen in the center
of this image, was named by the famous American explorer John Wesley Powell,
for its intimidating, rugged terrain. Eighty miles long and nearly as deep
as the Grand Canyon, it is one of the largest unprotected wilderness areas
in the West.

This image shows the Green River cutting a path through the vegetation of
the Plateau. The river appears blue while the vegetation is red. Snow dusts
the peaks of the Roan Cliffs, which appears light blue to white.

This image was acquired by Landsat 7?s Enhanced Thematic Mapper plus (ETM+)
sensor on December 31, 2000. This is a false-color composite image made using
near-infrared, red, and green wavelengths. The image has also been sharpened
using the sensor?s panchromatic band.
