Halema`uma`u Crater Ringed by Remains of Old Lava Lake...

Detailed Description

Red arrows point to the "bathtub ring," or high-lava mark, from the 1967-68 eruption in Halema'uma'u Crater. The light-colored ring, composed of rocks altered by acidic gases, is obscured in places by later rockslides from the unstable crater walls.
