The tallest waterfall in the United States is Yosemite Falls, located in Yosemite National Park, California. With a total height of 2,425 feet (739 meters), it consists of three distinct sections: the upper fall, the middle cascade, and the lower fall. Yosemite Falls is fed primarily by snowmelt from the Sierra Nevada mountains, causing its flow to vary dramatically throughout the year. During spring, when snow melts, it boasts a spectacular display of cascading water, while in late summer and autumn, the flow diminishes significantly. This iconic natural wonder attracts thousands of visitors annually for its breathtaking views and hiking opportunities.
