NEAR KAPALANA, HAWAII

Rough, clinkery "aa" flow moving over earlier, smooth "pahoehoe" flow above Kalapana on February 15, 1990. Note clinkered surface and the crags on the upper surface of the aa flow. Note also the very ropy surface of the pahoehoe flow. Photo Credit: J. D. Griggs, Hawaiian Volcano Observatory, U. S. Geological Survey
