On my last visit a few weeks ago, Halemaumau Trail was closed at the seam where the trail’s descent through a shady rainforest met up with the desolate crater floor, a demarcation line as distinct as blue and red in this upcoming election. A few years ago, a lava lake at the southeastern end of Halemaumau Crater started to generate excitement. It split open the crater floor and has grown to nearly 500 feet in diameter and more than 600 feet deep. This “pit within a pit” is the reason for the glow that is visible after sunset from the Jagger Museum. This week, I read that the level of this lava lake was rising quickly and threatened to flood the floor of Halemaumau Crater.
