Solid Rock is Not Forever

Living with active volcanoes, one gets to see new landforms appear regularly. The landscape can get rearranged with little notice, with places I once visited buried under new rock. In my time living on Hawai’i, I have seen roads, bays and tide pools, and entire neighborhoods disappear under new lava. Watching new land created by these flows of liquid rock is mesmerising.

The opposite is also true around here, sometimes prominent landforms are erased by the actions of flowing water, or the incredible power of wind and wave.

Thus we bid farewell to the Hōlei Sea Arch, cast into the sea by the heavy surf generated by Hurricane Nolo.

The arch was one of the features of Hawaiʻi Volcanoes National Park found along Chain of Craters Road. Featured on park maps and served by a viewpoint and interpretive signs, thousands of tourists have stood atop the cliff to admire what waves had sculpted from the jagged black sea cliffs.

Those same waves have erased what they carved. Sometime around September 27th, the arch fell into the sea. Apparently, no one witnessed its fall, there are no Facebook posts or YouTube videos of falling rock. All we have are before and after photographs. This is understandable as the park was closed during the hurricane.

I last visited the arch over a year ago, travelling the park with my parents. It had been noticeably eroded by the waves, appearing much thinner around the base than on previous visits. It was only a matter of time.

I had skipped or even aborted going to several recent episodes as conditions looked bad. When Episode 42 looked imminent, I was packed and ready to go. Then I looked at the winds… From the south. I aborted before ever leaving the house. A good decision, it rained rock in the main section of the park and on the viewpoints, thus the park and the highway were quickly closed.

Episode 43 occurred in heavy rain, while episode 44 was a repeat of 42 with tephra blowing to the northeast, prompting the park and highway to be closed again. Based on the chatter, I think most of the volcano junkies on-island were feeling a bit of frustration.

With another eruptive episode looking likely, I put my boss on notice that I might just collect that day off I was owed. Waking to a 2 am alarm, I rolled over, grabbed the iPad and checked the USGS webcams… We have a go!!
