Scientists from the University of Mexico reported Thursday that the Grand Canyon began being formed 17 million years ago, nearly three times longer than previous scientific consensus dating the canyon's formation to only 6 million years ago. The researchers based their conclusions on new findings obtained through a dating technique called uranium-lead isotope, which they used to date mineral deposits in the canyon's walls over a 9-state area.  The deposits came from cave formations in...

PHOENIX -- Scientists at the Grand Canyon plan to spend the next few years measuring air quality to see whether the closure of an aging coal-fired power plant improves the views. The Mohave Generating Station in southern Nevada closed Dec. 31 rather than meet a court-ordered deadline to install pollution-control measures estimated to cost $1.1 billion. The plant opened in 1971 and has been blamed for degrading views in the western Grand Canyon. "More than any other park, people go there...

GRAND CANYON NATIONAL PARK, Ariz. (AP) -- The South Rim of the Grand Canyon has long been a favorite of human visitors gawking at the stunning views and taking advantage of the manmade services. As it turns out, the South Rim also is a favorite of endangered California condors - for many of the same reasons. The large birds often gather to watch people, socialize with one another and drink from a leaky water pipe. On some days, as many as 25 to 30 condors soar over the canyon area - more...

GRAND CANYON NATIONAL PARK, Ariz. -- Mounted at about ear level on tripods, microphones are capturing the sound of quiet at the Grand Canyon. The four microphones are attached to sound level meters and computers that will later screen out all manmade sounds, such as the chatter of hikers, the rumble of cars and the buzz of sightseeing planes and helicopters. All that will be left will be the sounds of nature: the wind in the trees, the chirping of birds, for example. Park officials are...
