This Monday Oct. 22, 2012, photo shows a mule team walking along the Bright Angel Trail on the South Rim of the Grand Canyon National Park in Arizona. Search engine giant Google is using the Trekker, a nearly 40-pound, backpack-sized camera unit, to showcase the Grand Canyon’s most popular hiking trails on the South Rim and other off-road sites. It’s about 4 feet in height when set on the ground, and when worn, the camera system extends 2 feet above the operator’s shoulders. (AP Photo/Rick Bowmer)
