Havasupai is roughly translated as “The people of the blue-green
waters,” which refers to the beautiful turquoise color of Havasu Creek located at the bottom of the Grand Canyon.
The color of the water is the result of having been stored underground –
in limestone caverns or aquifers – for as much as 30,000 years. While
underground, the water leaches out minerals, primarily calcium and
magnesium, from the limestone. These minerals saturate the water and
reflect sunlight, making the water a turquoise color.
