FILE - In this June 30, 2007 file photo, climbers on the cable section of Half Dome negotiate the steep granite pitch in Yosemite National Park, Calif. A climb up Half Dome was once only for the most seasoned outdoors people, but in recent years tourists and weekend warriors have been scaling it with the aid of steel cables. When daily traffic on the route reached 1,200 in 2009 and hikers routinely backed up like cars at rush hour, park officials realized something had to be done.
