Do you want to guess how tall Mount Rainier is and how it ranks compared to other peaks in the U.S. (excluding Alaska because it has so many tall peaks)? For example, is Mount Rainier the tallest? Or are there higher peaks?
Mount Rainier is 14,417 feet high. It's the fifth highest peak in the "Lower 48." Mount Whitney (in California) is the tallest at 14,505 feet, followed by three peaks in Colorado — Mount Elbert at 14,440 feet, Mount Massive at 14,428, and Mount Harvard at 14,421 feet.
