The highest waterfall in North America is Yosemite Falls, located in Yosemite National Park in California. It has a total drop of 2,425 feet (739 meters), making it not only the tallest in North America but also one of the tallest waterfalls in the world. The falls consist of three sections: the upper falls, the middle cascades, and the lower falls. Yosemite Falls typically flows year-round, but its flow varies significantly depending on the season, with peak flow occurring in the spring due to snowmelt from the Sierra Nevada mountains.
