Canyon Village Area - Yellowstone National Park About Grand Canyon of the Yellowstone The specifics of the geology of the canyon are not well understood, except that it is an erosional feature rather than the result of glaciation. After the caldera eruption of about 600,000 years ago, the area was covered by a series of lava flows. The canyon below the Lower Falls was at one time the site of a geyser basin that was the result of rhyolite lava flows, extensive faulting, and heat beneath the surface (related to the hotspot). According to Ken Pierce, US Geological Survey geologist, at the end of the last glacial period, about 14,000 to 18,000 years ago, ice dams formed at the mouth of Yellowstone Lake. The colors in the canyon are also a result of hydrothermal alteration.
Grand Canyon National Park Location: Arizona Established: February 26, 1919 Size: 1,217,403 acres The road to the Grand Canyon from the south crosses a gently rising plateau that gives no hint at what is about to unfold. You wonder if you have made a wrong turn. All at once an immense gorge a mile deep and up to 18 miles wide opens up. Nearly five million people travel here each year; 90 percent first see the canyon from the South Rim with its dramatic views into the deep inner gorge of the Colorado River. It's hard to look at the canyon and not be curious about geology. Did You Know?

About Grand Canyon, Wildlife, Vegetation, History, Timeline & Architecture The Grand Canyon is probably the world’s most spectacular example of the power of erosion. Scientists estimate the Grand Canyon began forming 6 million years ago with the downward cutting (erosion) of the Colorado River, which flows through the Canyon. The work is by no means finished. The powerful forces of the river, rain, snow, heat, frost and wind are still sculpting the fantastic shapes of precipitous bluffs and towering buttes. Home to 88 species of mammals, 56 species of reptiles and amphibians, and 17 species of fish (the Humpback Chub and the Razorback Sucker are on the US endangered species list). The rare Brady Pin-cushion Cactus was discovered in 1958. Along the Southern Rim are several structures built by Mary Jane Colter and are on the National Register of Historical Places. The oldest human artifacts and split-twig figurines found, left by Desert Archaic Cultures, are between 3,000 and 4,000 years old. Grand Canyon Length: 277 river milesAverage width: 10 mi.
