The platform overlooks the remains of a trench that flowed full of lava at the time of the eruption, delivering million of gallons of molten fluid. When trenches such as these become roofed over, they are called lava tubes and the cooled remains are preserved as caves, such as Nahuku, or Thurston Lava Cave up on Crater Rim Drive. When the vent supplying the lava stops producing, these structures drain empty and cool. Large lava cascades may flow at a velocity of several to tens of miles per hour, however, in Hawaii, most flows can easily be outdistanced on foot.
