worlds tallest waterfalls by tallest free-falling drop
List of waterfalls with a free-falling drop of at least 500 feet in height. Only waterfalls which drop at an angle over 85 degrees perpendicular to the flow of the watercourse are considered for this list (we allow for slightly less than 90 degrees because there are very few waterfalls which drop a true 90 degrees). Waterfalls with more than one tier qualify for this list as long as all tiers drop over 85 degrees.
