The key idea is identifying the tallest waterfall by its total vertical drop within the 48 contiguous states. Yosemite Falls in Yosemite National Park, California, has a combined drop of about 2,425 feet, made up of several cascades (Upper Fall, Middle Fall, and Lower Fall). That total surpasses other well-known waterfalls in the continental United States, which is why Yosemite National Park is the correct choice. The other options are either located in Alaska (outside the contiguous U.S.) or have falls that are significantly shorter than Yosemite Falls, so they don’t hold the record for the contiguous states.
