Mount Thor in Canada has the world's longest vertical drop, with a potential fall of over a kilometer.

Mount Thor in Nunavut, Canada, is widely recognized for having the longest vertical drop on Earth, measuring approximately 1,250 meters. Multiple sources including Wikipedia and LiveScience validate this. The drop is characterized by a steep overhang, making it a notable feature for climbers. The second claim about falling over a kilometer aligns with the dimension of the vertical drop, but it should be considered more impressionistic since various factors could affect an actual fall. The supporting evidence is strong and corroborates the factuality of these claims.
