"As the largest protection, restoration and improvement project in park history, this milestone reflects the unbridled passion so many people have to care for Yosemite so that future generations can experience majestic places like Mariposa Grove," Michael Reynolds, Yosemite National Park superintendent, said in a statement. "These trees sowed the seeds of the national park idea in the 1800s and because of this incredible project it will remain one of the world’s most significant natural and cultural resources."
The re-opening is well-timed with the launch of the National Park Service's "Find Your Park" campaign, which includes an Instagram photo contest. The Grove's Tunnel Tree is pretty damn photogenic. Mariposa Grove is home to around 500 giant sequoias, which are among the largest living things on the planet.
