On 21st August 2010, I sat by the Delicate Arch at the Arches National Park, and watched the sun set. This is the video my time-lapse camera made.

This is a HD video so you can switch to 720p resolution from the drop-down box.
Although the people move around rather swiftly, you can certainly enjoy the slow crawl of clouds and shadows across the scene.
