It's not a typing error - there is no apostrophe in the name of this canyon. It doesn't belong to the king, but instead is named for a river, which in turn was named for the three kings in the Biblical story. According to the diary of Padre Munoz who traveled with the Moraga Expedition in the early 1800s, the first name Europeans gave the nearby river was Rio de los Santos Reyes (River of the Holy Kings).
Kings Canyon is a glacier-carved valley flanked by spectacular, tall cliffs with the Kings River flowing through it. A few miles outside boundary of Kings Canyon National Park, it deepens to become what is by some measures the deepest canyon in North America.
