What is a smoke that thunders?

"Smoke that thunders" is a poetic phrase often used to describe Victoria Falls, located on the border between Zambia and Zimbabwe. The term captures the sight of the massive water plumes and mist created by the falls, which can be seen from miles away, resembling smoke. The thundering sound refers to the roar of the water as it cascades over the cliffs, creating an awe-inspiring natural spectacle.
