The massive wildfire threatening Yosemite National Park continues to burn out of control.
It is now the largest wildfire in the history of the Nevada range. As many as 20 helicopters and air tankers are on hand, aiding the efforts of 3,800 firefighters.
The blaze is now only 20% contained.
Casey Wian is on the ground, as close as he can safely get to the flames with the latest.
