Honaunau National Park
Neptune Charlies boating and snorkeling with three species of dolphins, and a few Manta Rays too. A view through a monocular of a smoldering volcanic crater, and the regrown jungle around the Thurston Lava Tubes.
Halemaumau (house of eternal fire) boiled with lava from 1823 to 1924, when contact between magma and groundwater set off a chain reaction of massive steam explosions. 1000m high ash clouds rained mud, flashed lightning, hurled an 8000kg boulder 300m and doubled the width of the crater to 800m. Nearly a dozen eruptions since 1924 have continued to transform the crater, and a 2008 explosion welcomed a new era of lava activity that still churns today.
Also after dark I got a creepy photo of the lava-lit smoke and a disembodied man’s head.
