Not only is Yosemite one of California's most popular National Parks, but it's also a place where you can see some of Mother Nature's strangest phenomena.

They're not really trees, but they're the next-best thing when no real ones are around, and Joshua Tree National Park is full of specimens of Yucca brevifolia, a large, spiky-leafed plant which can grow up to 40 feet tall and lives only in the Mojave Desert. And this spring, they're putting on an unprecedented spurt of blossoms. Typically, only a few flower at a time, with only a few branches of flowers. This year, folks report that nearly every branch of every tree is in full bloom. You can read more about this natural event at National Geographic.
