When Kilauea Iki (Little Kilauea) burst open in a fiery inferno in November 1959, it turned the crater into a roiling lake of molten lava and sent 1900ft-high fountains of lava into the night sky. At its peak, the eruption gushed 2 million tons of lava an hour and the landscape glowed an eerie orange for miles.
From the overlook, you can view the steaming mile-wide crater below, used for filming the 2001 remake of Planet of the Apes .
