In 2023, Victoria Falls reached a geological age of approximately 150 to 200 million years in terms of the underlying basalt rock, though the current "falls" formation is much younger. The Zambezi River has been eroding the rock to create a series of eight different gorges over the last 100,000 years. From a "discovery" perspective, 2023 marked the 168th anniversary of the first recorded sighting by a European, David Livingstone, who arrived in November 1855 and named them after Queen Victoria. To the local Lozi people, the falls have been known for millennia as Mosi-oa-Tunya ("The Smoke That Thunders"). In 2023, the falls continued to be a dynamic natural wonder, with the geological process of "retreating upstream" still active, albeit at a rate invisible to the human eye. This milestone year saw the falls maintaining their status as one of the world's most ancient and powerful aquatic displays, bridging prehistoric volcanic history with modern global tourism.
