This natural-color image of Hells Canyon was captured by NASA’s Landsat-7 satellite on September 19, 2002. The image shows the northern part of the canyon, where the Imnaha River joins the Snake River.
The Green River in eastern Utah once carved soft sediment into meanders on a floodplain. Then the land and mountains rose and the river dug deep, preserving those meanders in stone.
Grand Canyon National Park spans 277 river miles and often stretches 10 miles wide. But the true wonder arises from its depth...or height, depending on where you stand.
The geology of the Grand Canyon has amazed visitors since John Wesley Powell first navigated the Colorado River in 1869. Now the Landsat Data Continuity Mission (LDCM) offers a new view of the gorge.
he largest tributary of the Colorado River between Lake Powell and the Grand Canyon, the Paria River flows southeast from its headwaters in southernmost Utah to join the Colorado River between Page, Arizona, and Marble Canyon. The Paria River provides spectacular scenery, and is known for the very narrow “slot” canyons that it cuts through the layered rocks of the Colorado Plateau.
