Yosemite Falls webcam joins park-peeking cameras across the U.S.

The cameras are positioned to maximize the changing light and seasons.

Associated Press reports that the camera joins a smattering of others across the nation. One of the most popular webcams in a national park has been one showing sled dog puppies at Denali National Park and Preserve in Alaska.

But not all are quite so fetching. At Glen Canyon National Recreation Area, a webcam shows traffic on the boat launch ramp at Bullfrog, Utah. One webcam at Sequoia Kings Canyon national park provides a view of a single oak tree so students can monitor its life cycle. At Little Bighorn National Monument, a camera offers a distant, grainy view of the military cemetery.
