Senior Vice President of Conservation at American Rivers Chris Williams announced today on the Google Maps blog that the organization has partnered with Google to add high-resolution imagery of the Colorado River running through the Grand Canyon to Street View:

Street-View-Colorado-RiverFor 6 million years, the Colorado River has flowed through the heart of the desert southwest, its waters slowly carving out a canyon so vast it can be seen from space—yet so remote it didn’t appear on early maps of the region. It wasn’t until 1869, when John Wesley Powell led a small exploration party on a rafting trip, that the natural wonders of the Colorado River and the Grand Canyon came fully into view.

Start at an iconic spot like Deer Creek Falls or North Canyon, or climb up to the Nankoweap Granaries. Geology fans will enjoy formations like Hermit Shale and Tapeats Sandstone. On your journey, look out for wildlife like big horn sheep and signs of a volcanic dam that naturally occurred centuries ago.

The project was an important one, as Google noted in its blog post, the Colorado River has long been at risk:

While you admire its grandeur, remember that the river is also at risk. One of the United States’ most important resources, the Colorado River provides drinking water for 36 million people from Denver to Los Angeles, supports a $26 billion recreation industry, and irrigates nearly 4 million acres of land that grow 15 percent of our nation’s crops. But it’s also one of the most endangered, dammed, diverted and plumbed rivers in the world, thanks to a century of management policies and practices that have promoted the use of Colorado River water at an unsustainable rate. By the time it reaches the Gulf of California in Mexico, the river is barely a trickle—a ghost of its once magnificent self. You can see evidence of the river’s decline In Street View, like the high water mark (showing 1950s driftwood on top of the rock), or sedimentation along the river’s edge down by Lake Mead.

Google has a new collection of imagery from the Colorado River here and a new webpage taking you behind the scenes of the project here.
