| Title: | PAHOEHOE LAVA FLOW |
| Caption: | The basaltic lava flow surrounding and destroying this home at Kalapana, Hawai'i, in 1990 has the characteristic smooth surface texture of most pahoehoe. Such flows destroyed more than 100 structures, including the National Park Service Visitors Center. Some pahoehoe flows are referred to as ropy lava because the surface texture can look like a piece of rope lying side by side as if it were coiled. (Paul Richards/© Bettmann/Corbis) |
