A new video has just been released today by Steve Bumgardner, who has lived and worked in Sequoia and Yosemite Park for over 20 years. I recommend this whole series highly because of his filmmaking skill using new timelapse techniques that bring the park to life. I keep a page with the entire series of Yosemite Nature Notes in the Cool links tab.  Thanks, Steve!

Episode 17
Black Oaks

Changing appearance throughout the seasons, the Black Oak is one of the iconic trees of Yosemite Valley, and its acorn is used for food by both animals and people.
