  • Lots of Grand Canyons

    Institute for Creation Research ^ | June 2014 | John D. Morris, Ph.D.
    Lots of Grand Canyons by John D. Morris, Ph.D. * On the seminar trail, I and other ICR speakers often use Grand Canyon as an example of Flood-caused geological features. We frequently run into opposition from people who’ve been taught that it took millions of years for the canyon to be carved out. We counter with studies that lead us to believe that each of the pancake-like layers was rapidly deposited by catastrophic hydraulic forces, and that the igneous and metamorphic deposits were caused by events quite unlike anything we see in modern times. The continent-wide coverage of the layers...

    Don't Grand Canyon Rocks Showcase Deep Time? by Brian Thomas, M.S. * Most Christians probably perceive the immense rock layers displayed in Arizona’s Grand Canyon as icons of “deep time,” marking the passing of millions of years. For example, respected Christian apologist William Craig wrote in 1974 that “the beautifully layered sediments evidence a slow process of formation.”1 Did beautiful layers like these require deep time to form? Not according to field observations or lab studies. A violent mudflow from a Mount St. Helens eruption deposited fine layers in less than a day.2 And water flume studies recreate the fast-flow...

    The canyon, found by airborne radar data, has the same characteristics of a winding river channel like the Grand Canyon in Arizona. It is at least 750 kilometers (460 miles) long, making it longer than the Grand Canyon. In some places, it is as deep as 800 meters (2,600 feet), on scale parts of the Grand Canyon. This immense feature is thought to predate the ice sheet that has covered Greenland for the last few million years.

In an unofficial time of 22 minutes, 54 seconds, Wallenda crossed a quarter-mile tightrope 1,500 feet above the Little Colorado River Gorge near the Grand Canyon. Wallenda paused and knelt twice to get “the rhythm out of the rope” and murmuring prayers to Jesus almost constantly along the way. His stepped slow and steady, but jogged and hopped the last few steps. “Thank you Lord. Thank you for calming that cable, God,” he said about 13 minutes into the walk. The stunt comes a year...

    SALT LAKE CITY -- A puppy rescued from the bowels of a deep slot canyon is now recovering in Salt Lake City after a close brush with death. The man who rescued him documented much of the incredible story with his own video camera. Imagine trying to get a dog that's near death out of a deep canyon, all by yourself -- and at the same time, getting yourself out by rope. On top of that, imagine shooting video much of the time. That's the story we have to tell. They don't know his real name, so they just call...

    In the summer of 2002, a week of heavy rains in Central Texas caused Canyon Lake -- the reservoir of the Canyon Dam -- to flood over its spillway and down the Guadalupe River Valley in a planned diversion to save the dam from catastrophic failure. The flood, which continued for six weeks, stripped the valley of mesquite, oak trees, and soil; destroyed a bridge; and plucked meter-wide boulders from the ground. And, in a remarkable demonstration of the power of raging waters, the flood excavated a 2.2-kilometer-long, 7-meter-deep canyon in the bedrock.

    Philip Coppens ^ | 04 Aug 2009 | Philip Coppens
    Is there, within the Grand Canyon, an enigmatic system of tunnels that is evidence of an ancient Egyptian voyage to America? Is it all bogus? Or is the truth most likely somewhere in between? On April 5, 1909, a front page story in the Arizona Gazette reported on an archaeological expedition in the heart of the Grand Canyon funded by the Smithsonian Institute, which had resulted in the discovery of Egyptian artefacts. April 5 is close to April 1 – but then not quite… so perhaps the story could be true? Nothing since has been heard of this discovery. Today,...

    HEREFORD — Nearly three decades ago, a two-story barracks on Fort Huachuca was carefully dismantled. There was no tearing the structure down without regard for ensuring the pieces couldn’t be used again. For 78-year-old Darl Goode, the object was to reassemble, with slight modifications, the structure on a piece of property off of Green Oak Lane in Stump Canyon. The old barracks, once part of what was called Splinter Village on the post, wooden structures constructed in the 1940s to house two black divisions that trained in Arizona during World War II, was put together on an acre of land...

    WELLINGTON, Utah - Along Utah's Nine Mile Canyon lies what some call the longest art gallery in the world — thousands of prehistoric rock carvings and paintings of bighorn sheep and other wildlife, hunters wielding spears, and warriors engaged in hand-to-hand combat. But now, a dramatic increase in natural gas drilling is proposed on the plateau above the canyon, and preservationists fear trucks will kick up dust that will cover over the images. And they worry that one possible solution — a chemical dust suppressant — could make things worse by corroding the rock. "They're irreplaceable," said Steve Tanner, a...

    More than two years after a precedent-setting move by the federal government cleared a path around environmental laws and legal challenges, the construction of a stretch of border fence across a deep canyon known as Smuggler's Gulch is set to begin next month. The project will require cutting earth from surrounding hills and filling in the canyon with more than 2 million cubic yards of dirt, an operation so large that critics fear disastrous environmental consequences. According to the latest plans from the U.S. Customs and Border Protection, the project will consist of constructing an earthen berm across the canyon...

    Grand Canyon Gorge Is 9 Times Older Than Thought Hope Hamashige for National Geographic NewsApril 9, 2008 New research on the Grand Canyon challenges the long-held belief that the canyon was carved by the mighty Colorado River about six million years ago. Parts of the canyon were formed more than 50 million years earlier than previously thought, according to the new study. The newfound evidence, which will be presented in the May issue of the Geological Society of America Bulletin, shows that part of the canyon known as Upper Granite Gorge formed more than 55 million years ago.

    TUCSON, Ariz. (AP) - Aravaipa Canyon, a coveted southern Arizona hiking spot, is no longer what it used to be. The area's wet summer dramatically altered the wilderness area about 50 miles northeast of Tucson, creating possibly record creek flows that scoured vegetation from the stream bed of Aravaipa Creek and flooded homes and ranches at the mouth of its 11-mile wilderness canyon.[snip]Scientists are still measuring the flood. The streamflow gauge recorded 6,000 cubic feet per second before it was washed away. The preliminary estimates of the U.S. Geological Survey were between 18,000 and 25,000 cubic feet of water per...

    This is one of the better pictures of the Upper Falls I could find. The Upper Falls don't get nearly the publicity or the views of the Lower Falls, but they are very dramatic. Because they don't get the publicity, they also don't get as much coverage by professional photographers, so a lot of the images on the Web are digital and don't really capture their beauty. Note the people on the edge-of-the-falls overlook for scale.
