A wildfire that spread more than 700 acres has led to the closure of Mariposa Grove in Yosemite National Park in California. Firefighters are scrambling to protect the giant sequoia trees. An estimated 1,600 people were forced to evacuate from a nearby community and campground. All of Yosemite is under “extreme” or “exceptional drought,” according to the California Drought Monitor. The dire condition is primed with no rainfall in recent months. » Subscribe to NBC News: http://nbcnews.to/SubscribeToNBC » Watch more NBC video: http://bit.ly/MoreNBCNews NBC News Digital is a collection of innovative and powerful news brands that deliver compelling, diverse and engaging news stories.
