If you were asked the question to name a famous
canyon, your answer is likely to be The Grand Canyon. If you were asked to
name another one, you probably wouldn't be able to. So, seeing as it's
obvious that nobody is really bothered about knowing about other canyons,
here are ten facts about most famous of them all: The Grand Canyon.
