Waimea Canyon

Waimea Canyon, also known as the Grand Canyon of the Pacific, is a large canyon, approximately ten miles long and up to 3,000 feet deep, located on the western side of Kauaʻi in the Hawaiian Islands of the United States. Waimea is Hawaiian for "reddish water", a reference to the erosion of the canyon's red soil. The canyon was formed by a deep incision of the Waimea River arising from the extreme rainfall on the island's central peak, Mount Waiʻaleʻale, among the wettest places on earth.
