I injured my knee recently, something I wouldn't be talking about here except that it gave this normally mobile person a good excuse to research the ins and out of visiting Disneyland when it's harder to get around on your own two feet.

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.

The Joshua trees aren't sturdy enough to climb, but the national park's rock formations here are, making Joshua Tree also a popular destination for rock-climbers. And the whole place is great for photographers. Take a look at a few of our Joshua Tree photos.
