If you ask the average person what the tallest mountain in the world is, they’d more than likely say Mt. Everest, and they’d be right….sort of. Everest is over 29,000 ft. above sea level, but its base is part of the Himalayan mountain range, so it’s not as tall as Mauna Kea in Hawaii. From its base on the sea bed, it stands 33,000 ft. tall, even though only 14,000 ft. is above sea level. That means even though Everest is the highest point in the world, it’s not the tallest!
