* No official definition: There's no universally accepted definition of what constitutes a "canyon." Some definitions are based on depth, width, or geological formation.
* Variations in size: Canyons range from small, barely noticeable depressions to massive, breathtaking landscapes like the Grand Canyon.
* Difficult to survey: Many canyons are remote or inaccessible, making it difficult to accurately count them.
While we can't get an exact number, we can say that there are thousands, if not millions, of canyons around the world.
