What's the most beautiful thing you've ever seen?

Red Rock State Park in Arizona during monsoon season. The area is full of bowl-topped mesas, so when it rains the bowls fill with water and there are waterfalls coming down off all the mesas onto the red desert below. The contrast of the water, red earth and all the greenery coming to life with the rainbows [i]everywhere[/i] from the waterfalls was certainly one of the most stunningly beautiful things I've ever seen.

Ancient redwoods are right up there with it though, for very different reasons.
