The President being photographed is not any president but a 3500 year old one. The President tree is the giant sequoia located in the Giant Forest of Sequoia National Park in the United States, California. It is not the tallest giant sequoia tree in the world (75 m), but it is the third largest tree in the world.
The tree until now had never been photographed completely. A team of photographers from National Geographic and scientists from the Sequoia National Park to be the first to accomplish that feat. if you look carefully you can see the tiny scientists among the branches and leafs of the giant tree. I myself could find four of them, you are welcome to find more if you can.
