The American beaver is an appealing animal, with dexterous paws, curious eyes and paddle-shaped tail. But, these rodents, the largest in North America, were nearly wiped out by the early 1900s as trappers sent mass quantities of the thick brown pelts back East for stylish top hats.
Northern Arizona is full of river runners, many of whom take their dogs downriver with them. Whether it's the Verde or the Salt River, many a mutt has gone along for the ride. And though dogs aren't allowed on the Colorado River in the Grand Canyon, commentator Scott Thybony says that doesn't mean it hasn't been done.
The Hualapai tribe has temporarily postponed upriver rafting trips in the Grand Canyon. As Arizona Public Radio’s Parker Olson reports, the suspension comes after the National Park Service voiced concerns about upriver travel.
A proposed development project near the confluence of the Colorado and Little Colorado rivers is one step closer to becoming a reality. But, as Arizona Public Radio’s Ryan Heinsius reports, several key questions still remain about the controversial, multimillion-dollar development.
There was a time when scientists feared the demise of an ugly little fish called humpback chub, which has lived in southwestern rivers for millions of years. One of its last holdouts is in the Grand Canyon section of the Colorado River at a major tributary, the Little Colorado. Glen Canyon Dam took its toll on the little fish, and by the late 1990s, its population plummeted to a few thousand.
But these days, the humpback chub appears to be making a comeback.
The Colorado River is about to run wild again, at least a couple times a year. In May, Interior Secretary Ken Salazar approved a series of simulated floods -- releasing huge amounts of water and sediment from the Glen Canyon Dam over the next several years. It’s all part of a long-studied effort to restore the river environment downstream.
Five boats recently launched a two-week Grand Canyon river trip. The group of tourists paddled white-water rapids, hiked side canyons and camped at river’s edge.
