  • Fort brush fire contained, 1,400 acres burned

    Sierra Vista Herald ^ | Derek Jordan
    SIERRA VISTA — A brush fire scorched more than a thousand acres and threatened homes on Fort Huachuca after burning throughout the day and into the evening Wednesday, leading to some residents being notified to be prepared for a possible evacuation, though one was never ordered. The fire was first reported at Range 10 shortly before 10:50 a.m. and is believed to have been started during training. “There was a military unit conducting weapons qualifications on the range,” said Angela Camara, public affairs office for Fort Huachuca. The fire soon spread toward Garden Canyon Road, leading to its closure, while...

    The worlds largest canyon may lie deep beneath the ice sheets on Antarctica, according to a new discovery by UK scientists. While the depth of the discovery is comparative to the Grand Canyon it dwarfs the US landmark by 555km in length. Satellite data recovered by a team of scientists led by Durham University revealed the previously unknown canyon system which is thought to be more than 1000km long and 1km deep buried under several kilometres of ice. While the discovery is yet to be confirmed by direct measurements, researchers believe the canyon beneath the ice sheet may be so...

    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.

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.

    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...

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.
