PBS - Denali, Alaska's Great Wilderness
Denali National Park and Preserve spreads out across 6 million acres in the Alaskan Range, a 600-mile arc of mountains that divides south-central Alaska from the interior plateau.
Only one PBS Screen Saver may be used in the control panel at a time. If you want to have more than one available, you should keep them in a separate folder on the hard drive, the desktop, or wherever the most convenient spot is.
Place the unstuffed copy of the screen saver in the Control Panels folder of your System Folder.
Turn off any other screen savers that may be running. Restart your computer.
You can trash the .sit file once the screen saver has been extracted.
