Chris gets a daily email from Ripley’s Believe It or Not! with an interesting fact. The one he got yesterday mentioned Niagara Falls:
The frozen waterfall of Mount Beardmore in the Antarctic has a height of more than ten thousand feetâ€â€sixty times that of Niagara Falls.
Mount Beardmore is essentially now a high glacier, but that sure is tall! Niagara Falls would look puny next to it.
