Kīlauea’s Night Skies: An Artist’s Perspective. Join Hawai‘i Island artist and interpretive guide Kent Olsen as he presents Kīlauea’s Night Skies: An Artist’s Perspective. Drawing on insights and perspectives developed through years of work in the medical imaging design field, as an interpretive guide at Mauna Kea Observatories and as a certified commercial guide at Hawai‘i Volcanoes National Park, Kent will present the night skies over Kīlauea in a way that is sure to provide a new perspective and may just change the way you see everything. Utilizing the current lava lake within Halema‘uma‘u Crater as a point of reference, you will journey from the depths of the quantum realm to the edge of the cosmos. Olsen boldly attempts to describe the natural world in a way that makes the scale of the seemingly infinite something you just might be able to wrap your head around. Attendees are reminded the park is open all night for stargazing and lava glow viewing. Part of Hawai‘i Volcanoes’ ongoing After Dark in the Park series. Free.

High-Altitude Stream Sampling at Haleakala NP… At the request of the park, the PACN recently sampled streams at high altitude in Haleakalā National Park on Maui. The team implemented the stream monitoring protocol at Palikea Stream, which is normally only sampled downstream near sea-level. The park was interested in what fish, snails, and shrimp might live in reaches far upstream.
This sampling trip was a true expedition into the wilderness, and required a lot of preparation. The team had to get trained on helicopter operations and safety. We prepared our normal stream sampling equipment, including a water quality sonde, flow meter, water sampling filter tower, and snorkeling gear.
A four-person, five-day trip to sample streams required two “sling-loads” of supplies. After arriving at the landing zone near the Kīpahulu Visitor center, we spread out two giant nets made of heavy rope. We arranged all our coolers, backpacks, and other supplies into the centers of the nets. Then the nets were closed around the supplies and fastened with heavy gauge steel cables.
The helicopter, bright orange with stripes, with a small bubble for a passenger and high skids, swooped in overhead and landed in the middle of the field. I was escorted to the door. I climbed in, put my harness on, and plugged my headset in. Or rather, I had help doing all these things, since it was my first heli-op. It was so noisy I couldn’t speak to anyone. Once my escort climbed in and got settled, up we went.
We soared over the rainforest climbing high into Kīpahulu Valley. There are no roads, no trails, and no real landmarks besides the streams and topography of the land itself. The flight only took about five minutes. We landed in a small patch of high grass among ‘ōhi‘a trees. My partner led me away from under the spinning rotors to the tree line. Once the rest of the team joined me, we made our way through the dense forest, climbing over roots and branches to our home for the next five days… Delta Camp. It’s a shack (photo on right) built in the forest with a single small room and a tank for catching rainwater.
Twenty minutes later, we heard the helicopter approaching, and it hovered directly over the camp. The rotor wash drowned out all other sounds and everything shook in the artificial wind. A sling load was lowered out of the sky onto the ground right next to the camp. The cable separated, and the ship flew away. We move all the supplies out of the way, and a second sling load arrived. As the ship left it toggled its siren to say farewell. The sound of rotors fades away.
We were there to survey Palikea Stream at an altitude of 4,000 feet. Between our location and the famous pools at ‘Ohe‘o several miles away are literally dozens of waterfalls; some several hundred feet high. But it was possible that fish were there, as some can configure their ventral fins to form a kind of suction cup, and literally scale vertical rock walls under waterfalls. We scouted the stream nearby, and decided it was suitable to sample. The next day we would scout another location downstream.
This place is cold and wet. The dense forest surrounded us with ‘ōhi‘a trees, hāpu’u, shrubs with wide succulent leaves, and stands of small climbing ferns. Bird songs abound, but it was difficult to spot them.
Our first survey revealed no fish in the stream. In fact there were no snails, no shrimp, and almost no algae growing on the rocks. It appeared as if the gravel and rocks in this area are repeatedly scoured, preventing biofilm from developing. We did find rare ferns along the bank, and a small aquatic beetle. This stretch of the stream ends in a tall waterfall. Perhaps the geomorphology of the stream is such that the water is concentrated in a small area, creating high turbulence that rolls the rocks and scours them clean.
The next day we moved downstream through the forest. It was slow going. We frequently had to crawl under brush and take detours around thick vegetation. We were headed for a spot on the map that looked to be safe access to the stream. When we arrived we looked down on the stream from the tops of cliffs. There was no safe place to access the stream, let alone sample, so we had to abandon this area. Another slog through the rainforest and we arrived back at camp. Fog rolled in, obscuring the surrounding mountains. We discussed our options and decided to try a different stream that runs parallel to Palikea, nicknamed ‘Ōpae Stream. Judging by the name we thought there ought to be shrimp. To get there we’d have to cross Palikea. It was a concern because if the water rose, we could be trapped on the other side. Had there been heavy rain overnight, and the Palikea was high, we wouldn’t have attempted it. By morning the weather stayed clear, and Palikea was flowing normally. We crossed and found ‘Ōpae Stream.
This stream is remarkably different. It flows through a flatter, more open area with trees. Moss covers rocks. There is algae growing on most surfaces. We did find shrimp, but no fish. Is there one particular waterfall that they can’t overcome somewhere downstream?
We explored upstream until we got to another several hundred foot waterfall. One biologist, who has worked in the area many times over the past twenty years removing invasive plants, had never been to the end of this particular stream. I wonder if the ancient Hawaiians pushed this far into the forest. We might be the first people to see this particular place in 500 years, or ever.
The information we gathered will help to characterize water quality, the physical habitat, and spatial distributions of animals populations in Kīpahulu Valley in areas never before surveyed. In future trips we will survey downstream to try and determine how far upstream stream animal populations extend.
The next day we broke camp, packed up, and carried every cooler and bag through the forest to the landing zone. It was time to head back. We were thoroughly tired, and thoroughly inspired.

What drew you to volunteer at Haleakalā National Park, Why have you come back for repeat seasons? I was drawn to volunteer at Haleakalā National Park because I wanted to gain work experience in the field of nature conservation and resource management. My position of wildlife management intern enabled me to do this while helping out with conservation projects that are important to me. The unique environment of Haleakalā appealed to me as well.
Last Friday, all of the national park staff picked-up trash along the road and harbor near the visitor center and headquarters. It’s part of our continued efforts to help keep American Samoa beautiful and to educate about the importance of putting trash in bins. Trash not only looks bad, but it also harms wildlife and coral reefs.
Before and after photos show our efforts to clean-up a stream. Do your part, wherever you live, to keep your special places trash free!

Volcano Watch (http://hvo.wr.usgs.gov/volcanowatch/) is a weekly article and activity update written by scientists at the U.S. Geological Survey`s Hawaiian Volcano Observatory.
The dramatic opening of the Overlook crater within Halema‘uma‘u Crater on March 19, 2008, heralded a new period of activity for long time Kīlauea Volcano watchers.
Over the next several years, nearly continuous eruptive activity formed an active lava lake in the new crater. An active lava lake is one that overlies its vent, which constantly supplies lava to the lake and drains lava from the lake. This circulation keeps lava in the lake hot and also generally keeps it from spilling from the crater. An active lava lake contrasts with a “passive” lava lake, which is simply a pool of lava formed when lava flows into a depression.
The active lava lake in Overlook crater is now the second largest lava lake on Earth, about 170 m by 220 m (560 ft by 720 ft) across. The lake is more than 100 m (328 ft) deep and Overlook crater itself deepened by 8 m (26 ft) in late April and early May 2015, when overflows onto the floor of Halema‘uma‘u built the rim higher.
Visitors to the summit of Kīlauea are now accustomed to the spectacular nighttime glow above the lake as it rises and falls in concert with summit inflation and deflation, as well as with expansion and episodic escape of gas bubbles.
Although relatively new to most of us, churning lava lakes are certainly not new to Halema‘uma‘u Crater. Indeed, from 1823 through 1924, a lava lake (or lakes) was nearly always present in the caldera, generally inside Halema‘uma‘u. Short-lived lava lakes played in Halema‘uma‘u several times between 1924 and 1968. Much of the time, however, visitors witnessed a scene quite different from today.
As one example, this nearly century-old print shows Halema‘uma‘u when much more of its floor was covered by a lava lake compared to today. Towering bodies of solidified lava called “crags” rise above the lake surface like battleships on the sea. At times these crags were so high that they could be seen by spectators at the old Volcano House nearly 3 km (2 mi) away. Visitors could sometimes view lava fountaining and hear noises of splashing lava from the hotel. Today, the clatter of breaking and falling rocks is, with favorable wind, audible outside Jaggar Museum, and the overflows in April–May were visible from many caldera vantage points.
In the early 1900s, the lava lake inside Halema‘uma‘u resembled a dynamic body of water in many ways. Thomas A. Jaggar, founder of the Hawaiian Volcano Observatory, used terms such as cove, bay, and inlet to describe lava pools and other features in the lake. The lava lake was typically impounded by levees made by overflows of lava from the lake, just as overflows of silt-laden water create levees along the Mississippi River.
This photograph shows what was known as the Southeast Crag, an 11-m- (36-ft-) high peak of solidified lava that had been twisted and tilted upward. As of yet, we’ve not seen any similar features developed in the current lava lake within Overlook crater. This may be because the present lake is impounded by the walls of Overlook crater, not by its own natural levees, which can change configuration and location with time. If such self-impoundment should develop in the Overlook lava lake, we may once again see crags, bays, and inlets.
We will share more of the rich photographic record of Halema‘uma‘u lava lakes from the last century in future Volcano Watch columns. Although they lack the vivid and mesmerizing colors of modern photographs, there is a stark beauty in these crisp, black and white scenes of lava in its myriad forms that we find equally compelling.
Kīlauea Activity Update
Kīlauea’s summit lava lake level fluctuated over the past week with changes in summit inflation and deflation, but remained well below the rim of the Overlook crater. During the past week the lake ranged between 40 and 65 m (130–210 ft) below the current floor of Halema‘uma‘u.
Kīlauea’s East Rift Zone lava flow continues to feed widespread breakouts northeast of Puʻu ʻŌʻō. Active flows remain within about 8 km (5 mi) of Puʻu ʻŌʻō.
One felt earthquake was reported on the Island of Hawai‘i in the past week. On Friday, June 12, 2015, at 1:07 p.m., HST, a magnitude-2.3 earthquake occurred 8.0 km (5.0 mi) east of Waimea at a depth of 13.0 km (8.1 mi).

Crater Road (Rt. 378) and Haleakalā National Park’s summit road will close to visitor traffic while a slow moving convoy transports extremely wide loads to the Daniel K. Inouye Solar Telescope near the volcano’s summit. The roads will be closed to visitors from 10pm on Wednesday, June 24, through 2pm on Thursday, June 25. The summit will not be accessible for Thursday sunrise viewing.
Back country permits will be given out at Headquarters Visitor Center (at 7000 feet of elevation), from 2pm-4:30 pm on Thursday. However, backpackers planning to hike into the crater on Thursday are strongly urged to obtain their permits a day in advance. Visitors who paid an entrance fee on Tuesday, Wednesday, or Thursday (June 23, 24, 25) will have a one-day extension on the usual three-day pass. The extension will apply to both the Kīpahulu and Summit Districts.
Although the park road to the summit will re-open at 2pm on Thursday, the Haleakalā Visitor Center (at 9740 feet of elevation), will remain closed all day.
The Advanced Technology Solar Telescope (ATST) Project is located outside of park boundaries. The convoy’s travel through the park is being allowed via Special Use Permit. The convoy will transport an 18-foot wide load and travel at 2 to 5 mph. The road precautions are in place due to the size of the convoy and narrowness of the roads. The convoy will include three semi-truck trailers and various support vehicles.
