Ropy Pahoehoe Lava

Ropy pahoehoe lava (lava with a smooth, billowy or ropy surface) on Kilauea, the youngest and southeastern-most volcano on the big island of Hawaii. Topographically Kilauea, which is located on the southernmost flank of Mauna Loa, was thought to be an extension of its giant neighbor.
