Along with witnessing a mind-boggling array of herbaceous monocots (orchids), and getting misty-eyed in the spray of the Rainbow Bridge's 80' cascade, we will spend a lot of time with lava, so let's get to know it.
When Earth has indigestion, it expels magma, which turns to lava as it nears the surface. In Hawaii, there are six forms of lava. Pahoehoe is usually smooth, billowy, and can resemble a brownie crust. In jagged contrast, 'A'a is covered with severe edges, and is tough to walk on. Pele's Hair looks like shimmering strands of wiry greenish-gold hair - created when molten lava explodes into the wind. Pele's Tears are droplets formed in lesser winds. Lava Bombs are giant tears, blobs of molten lava as big as cars; pray none land on you. Finally, Green Sand crystals come from peridot, a semiprecious form of olivine in the lava.
Just as lava varies, so do volcanic features. Calderas are like cauldrons, formed when a magma chamber empties and can't support the land above it. Pit Craters are small calderas, under a mile in diameter. Cinder Cones are small steep-sided conical volcanoes on the flanks of volcanic mountains. In contrast, Spatter Ramparts are elongated eruptions on a fissure's ridge. Solfataras are vents where stinky sulfuric steam escapes. Fumaroles are less sulfuric and can become hot springs. Tree Molds form when lava surrounds a tree, solidifies, and drains away, leaving a burned out trunk void. Lava tubes are underground caves stretched into tunnels by a lava-flow's deepening path. Ok, now that you are armed with the facts, are you ready to go explore?
Tough nut to crack
Nothing that comes easy is worth having right? Well, the tough outer shell of the macadamia nut requires 300 lbs. of pressure per square inch to penetrate the tough exterior revealing the sweet nut inside. If you can open one of these bad boys on your own, it’s definitely worth enjoying- or you could just leave it to the people at Mauna Loa Macadamia Nut Factory when you stop in for a visit.
