It's a mystery as to how this lake can even exist! Nobody knows exactly why the porous volcanic rocks in this area are holding water. Scientists believe it may be due to a layer of ash from an ancient eruption of Mauna Kea or possibly due to a layer of permafrost beneath the ground. It's a stark and stunningly beautiful location. A place sacred to some Hawaiians who still deposit their baby's umbilical cords in the lake. Be cautious of of the windy, cold conditions and the oxygen deprivation if you hike here. My husband was starting to lose part of his vision from lack of oxygen! He fully recovered when we got to a lower elevation.
