One out of a million…

One of the great motivators for a nature photographer is the potential for the unexpected. As much as I love planning my photo shoots, especially when things come together exactly as hoped, the euphoria of the unexpected feels like photography’s greatest reward.

Some natural phenomena can be predicted with surgical precision—events like a rising or setting sun or moon, a total solar eclipse, the moonbow that materializes every spring full moon at the base of Yosemite Falls, and the sunset light that colors Horsetail Fall in late February—with the only variable being whether or not the clouds will cooperate enough to allow us to view the show.

I love those reliable phenomena and have made my living scheduling photo workshops to share them with others. But I also have a few workshops scheduled around the hope of something spectacular—a high risk, high reward roll of the dice that can only be timed to provide the best chance of success. In this category I include the Iceland aurora workshops Don Smith and I do each year, my Grand Canyon monsoon workshops where we cross our fingers for lightning and rainbows, and my latest obsession, chasing supercells and tornadoes across the US and Canadian plains.

But let me submit a third category: those phenomena where there’s absolutely nothing strategic about the timing, and when it occurs, it feels like a gift from Heaven. I guess that could describe any random sunset, rainbow, or unexpected snowfall, but I’m thinking more about those one-out-of-a million phenomena that are so spectacular and rare, for many they’re a once in a lifetime event. Like an erupting volcano.

My personal volcano history

I’ve been visiting Hawaii’s Big Island every (non-Covid) September since 2010. Through 2017, the lava lake in Halemaʻumaʻu on Kilauea’s summit bubbled away 24/7, allowing each of my workshop groups to view and photograph beneath the Milky Way. This was so reliable, I simply took lava’s nightly glow for granted. Until 2016 I never saw actually the lava itself, just its rising smoke and vapor plume during the day, and the lava’s orange radiance illuminating the caldera walls after dark. But in 2016 the lava lake rose to the top of Halemaʻumaʻu and overflowed onto the caldera floor, and my group and I were gifted with the rare opportunity to view bubbling, exploding lava. Then in 2017 everything was back to normal, and my group returned to photographing the glow (and me to taking the eruption for granted).

But in a frustrating exhibition of Mother Nature’s fickle whims, in 2018 she reminded me to never take her for granted, and completely shut off the summit eruption the week before my workshop. Of course there’s lots of other stuff to photograph on the Big Island (my favorite Hawaiian island), but it’s pretty hard to top a volcanic eruption.

Since 2018, Kilauea has been mostly quiet, with a handful of relatively minor eruptions each year, most measured in hours or days, arriving with very short notice, and vanishing just as suddenly. In other words, impossible to plan a workshop around, and rare enough to never be expected.

My groups got nothing from the volcano in 2018, 2019, and 2021 (2020 was lost to Covid). Then in 2022, my workshop group and I were fortunate enough to get a long distance view of an eruption and the Milky Way from a brand new location. And in 2023 we hit the jackpot when a very active eruption started the day before my workshop, and ended the day after. For that one, I got to photograph numerous small fountains and lava rivers across a wide area of the caldera floor three different times, and my group enjoyed the same show twice. Then in 2024, Kilauea was quiet again.

I knew that Kilauea’s eruption history meant that the next one could be tomorrow, or years away. Or never. But in December of 2024, a whole new kind of eruption started on Kilauea. Instead of smaller fountains spreading across the caldera as we’d seen in 2023, this one was limited to one or two massive fountains. And instead of the recent one-and-done eruptions that would last for days or (occasionally) weeks, this new eruption came in short and sweet bursts separated by days. The first few lasted longer, up to 8 days, but after a while this latest eruption established a fairly regular routine, coming every week or so and lasting less than a day.

The fountaining in some of these episodes exceeded 1000 feet (a height I struggled to imagine, despite the many pictures and videos shared online), with most reaching at least 300 feet—far higher than anything I’d seen before, including in 2023.

Finally, we get to this image

(That’s a lot of context for just one image, so thanks for sticking with me.)

Since I scheduled the 2025 Hawaii workshop in the summer of 2024, I added it with no expectations of photographing an eruption. I simply knew any eruption, while always possible, was quite unlikely. Of course Hawaii has plenty to photograph without an erupting volcano, but a person can dream….

When the current eruption started late last year, nothing in recent history gave hope that it would last long enough to still be going by the time my workshop came around. With 10 months to go, my hope meter stayed pegged on zero. But as the volcano settled into its once-a-week routine and the months clicked past with little change in that pattern, I started to notice a slight quiver in the meter’s needle.

But as we all know, Mother Nature toys with hope. No sooner had my meter shown signs of life, the reliable one-week span between eruptions started stretching out to 10-14 days, the episode duration dropped to less than 12 hours, and the fountain heights dropped well below 500 feet. By the time episode 32 came and went in early September, I was down to hoping my workshop group would be lucky enough that the 12-hour or less span of the next episode (if there was a next episode), would fall sometime in the workshop’s 4 1/2 days. Not great odds, but to be safe, a few weeks before the workshop I e-mailed my group explaining our poor odds, but also reassuring them that if any eruption did happen during the workshop, we’d drop all other plans and I’d do everything in my power get us up to Kilauea to view it, regardless of the hour.

But in the secret recesses of my mind, despite my overwhelming desire to see and share this unprecedented sight, the possibility (no matter how small) that I might be responsible for navigating a dozen photographers and 3 vehicles through the mayhem reported to accompany every prior episode—gridlock and hours just getting into the park, no parking once we get in, and limited viewing space—was daunting at best. Combine that with the fact that I obsess about getting my eyes on a scene before guiding a group to it—not only did I not have any experience with the best viewing locations for this eruption (each eruption happens at a different location in or near the crater), if it did happen during the workshop, I’d be learning on the fly, with my group depending on me.

I did as much research and preparation as possible from 2600 miles away, scouring the internet, reaching out to others I knew who had viewed prior episodes, and practically memorizing the viewing instructions on the NPS Hawaii Volcanoes website. But I knew all this planning would be of little use if we made the 45 minute drive from our Hilo hotel to the park and found it teeming with double-parked photographers and gawking tourists.

Then, just a few days before the workshop, the USGS posted an eruption forecast stating that the earliest the next episode would start would be September 19, and possibly later if summit inflation (the amount of magma in the subterranean chamber) decreases. Since my workshop wraps up following the sunrise shoot on September 19, I knew we’d almost certainly miss it. A disappointment for sure, but also a significant stress reliever.

On my pre-workshop scouting visit, I learned that the vent of the eruption had been glowing the last couple of nights, a sign that the magma chamber was filling. With that information I realized there might be an opportunity to give my group a caldera night shoot for the first time since 2017. Not only that, as I scouted the views to the current eruption vents, I realized that I’d be able to align the caldera’s glow with the Milky Way, just like the olden days. Even without an eruption, things were looking up.

On Tuesday, our second night, I took the group to the caldera for sunset, and we stayed for a magnificent Milky Way shoot beneath a spectacularly (and unusually) clear sky. In fact, unlike all the prior Kilauea Milky Way shoots, where we just photographed a glowing hole at the bottom of a featureless caldera floor, subsequent eruptions (and especially the current one) had raised the caldera floor from 100 to 300+ feet, and replaced the dull rocks and shrubs with brand new beautifully textured lava. And the glow now emanated from a discernible volcanic cone that at times during our shoot emitted visible splashes of lava.

I went to bed that night overjoyed to have given my group an actual active volcano experience. And then I woke Wednesday morning. Checking the USGS Kilauea status update, I did a double-take. The earlier September 19 – 23 episode 33 forecast had been revised to indicate that an eruption was imminent, and could start any time from September 17 (today!) to 19. Whoa.

Along with the euphoria that we might indeed get to witness an actual fountaining eruption came the prior anxiety of not knowing exactly how I’d navigate it. So I devised a plan. Knowing that we’d all been up to the volcano the prior day, I decided that if the eruption does start, we’d drop everything and immediately beeline to Kilauea as a group, in no more than 3 vehicles (there were 14 of us, including me and my brother Jay). Once there, we’d do our best to stay together, but if it was too crowded and unmanageable, each car would have full autonomy to go where its occupants wanted to go, and to stay as long as they wanted. If that happened, we’d still keep in constant contact via our workshop WhatsApp group (which we’d already been using all week), and share any insights we learned about parking or vantage points. With a plan in place, we went about the day’s workshop plans (Akaka Falls and Hawaii Tropical Botanical Garden), keeping a constant eye on the USGS eruption webcams and status updates.

Nothing had happened by the end of the day, so before sending everyone off for the evening, I checked to see who wanted to be awakened if the eruption started overnight, and found that all but three were up for an overnight adventure.

At 11:30 p.m. I’d already been asleep for a couple of hours when my phone started lighting up with notifications that the eruption had started. We were awake, dressed, and on the road in 15 minutes. By 12:15 a.m. (Thursday morning) we in place at the caldera and clicking madly.

What we saw this evening was not the promised fountaining, but no one was disappointed by the bubbling vent, lava falls, and lava river we did see. The splashes this night reached up to 50 feet, and our vantage point at the Steam Vents gave us a perfect view straight to all the action. We stayed to photograph it until 3:00 a.m., and drove back to the hotel completely euphoric. Needless to say, we passed on the sunrise shoot.

Stay tuned for Part Two…
