Mauna Loa, one of the two 4000-meter peaks on the island of Hawai’i, is the largest volcano on earth, as measured by volume. It’s still active: the last flow, in 1984, came within 4 miles of the town of Hilo. Raw black lava flows mark its flanks, and sometimes you can see it smoking.
Up in the thin, dry air on Mauna Loa is a wilderness of brittle lava rock, an immense caldera, and harsh tropical sun. The temperatures are cold – it snows – and the wind howls, but the sun remains at its brutal tropical angle. Sounds like a fantastic hike, right?
You can’t not do it, though: a 4000-meter peak that’s not a technical climb is pretty much impossible for hikers like us to pass up. So Seth and I summited Mauna Loa in September 2018. After many months aboard CELESTE at sea level, it was quite the challenge….
