Kilauea lava reaches the ocean – part 1

On July 9, I posted about a visit to see the latest lava flow (exotically named the 61g flow) from Kilauea Volcano’s Pu’u O’o vent. At that time the lava was less than three-quarters of a mile from the ocean and I figured I’d go back when it got closer to the emergency road (about a tenth of a mile inland) and the water.

That, of course, was the cue for forward progress to cease. The flow was still active, but mostly in breakouts to the side. Day after day the lava was noted as being about half a mile short of the water. I checked again on Sunday, still no change. Monday, I forgot to look. So naturally, Tuesday’s lava report, not seen until the late afternoon, reported that the lava had reached the ocean at 1:15 that morning. Scratch the idea of being present when that happened.

However, my wife and I really wanted to see the lava’s ocean entry from the water and it sounded as though at least one boat tour company, Lava Ocean Guided Tours, was already running trips. A phone call later, we were booked on the sunrise trip the next morning. Check-in time was 4 a.m.. Current time was 5:30 p.m.. Drive time to the launch place is three hours – it’s the far corner of the island. That left seven and a half hours for getting organized and, oh yes, sleep.

Today’s photos show we made it. At the top is the view from the sea, and people ashore perilously close to the flow. Second photo is a frontal view. Below, the morning scene looking toward the sunrise. Tomorrow I’ll post more photos and details, but first, a good night’s sleep is in order.

Tree tobacco

Tree Tobacco (Nicotiana glauca) heralds from South America, but in Hawaii, it’s an invasive species.
Tree Tobacco (Nicotiana glauca) heralds from South America, but in Hawaii, it’s an invasive species. The chances of eradicating it are slight. Controlling its spread is a more realistic possibility. But tree tobacco is one invasive species in Hawaii that does have something going for it.

Enter Blackburn’s sphinx moth (Manduca blackburni), a large, endemic moth, once thought extinct, and a long-time resident on the endangered species list. Among its problems is that its host species, ‘aiea, (Nothocestrum spp.) has been on the decline for a while. ‘Aiea belongs to the nightshade family (Solanaceae) as does tree tobacco.

It seems that the moth, in the interests of survival, decided tree tobacco is not so bad. So we have an endangered species becoming reliant on an invasive species. Hmm. As I said, control is the most likely approach with tree tobacco and that will undoubtedly involve checking to see whether Blackburn’s sphinx moth is present before removing areas of tree tobacco.

That’s good news for the plant in this photo. I found it at Pu’u Wa’awa’a, a State Forest Reserve on the northern slope of Hualalai. Pu’u Wa’awa’a is home to a variety of endangered plants and animals including Blackburn’s sphinx moth.

The spooky horses of Waipi’o Valley

Yesterday, I posted about my hike into Waipi’o Valley. One feature of the valley is that wild horses live there. These appear to be ‘wild’ in the sense that they aren’t owned, but they’re not the wild mustangs of the wide open west.

I saw the first of them when I came to this large lake spanning the sandy road leading to the beach. At first I didn’t notice it, but as I looked for my best path around the pond, I saw it standing off to the side, by the trees. My best path would take me in the horse’s direction; the other side looked too muddy.

I looked at the horse again. It hadn’t moved. Not at all. Not a swish of the tail, not a flick of an ear. It was eerily still, so still I wondered for a moment if it wasn’t a super-realistic, life size model set there to disconcert tourists. No matter. I had to go by it and it would surely move then. As I approached, I spoke to it. Still nothing. I passed behind it. Not a twitch, not a blink. I walked to the other side of the road and took another photo. Nothing from the horse. A few more photos and finally the horse flicked its tail, the first sign of life since I initially saw it. After a while, the horse gathered itself, turned around, and eased into the trees.

Later, on my return after going a little way up the Muliwai Trail, I took the trail which runs through the trees behind the beach. A short way along the trail I just got a certain feeling. I turned around and there was a horse following me only about 10 feet behind. I hadn’t seen it. I hadn’t heard it. It looked at me, then turned toward the ocean. I walked on a few paces, then looked back. The horse was gone, nowhere to be seen.

There’s a 22 miles stretch of the northern Big Island coast, from Pololu to Waipi’o Valley, that isn’t accessible by car. At the southeast end of that stretch, the road ends at the Waipi’o Valley overlook. From there, a paved road descends into the valley. It’s rough, winding, and very steep. The average grade is 25%, steeper in places. Four-wheel drive and healthy brakes are a must.

The alternative is to hike into the valley, which is what I did. The road drops about 800 feet in just over half a mile. It’s hard on the knees, but easy on the eyes. There’s a gradual unfolding of details that aren’t visible from the overlook – fields, dwellings, horses. The valley, which is important in Hawaiian history, was wiped out in a 1946 tsunami. Now it’s populated by taro farmers and people who tend to shy from society. It’s a bit of a clash for it to be a popular tourist stop.

At the foot of the hill is a junction. The road continues straight on into the valley, but the public access soon ends. In the opposite direction the road heads to the sea. After a little under half a mile, the sandy, lake-filled road breaks out to the beach. There’s lots of parking under the trees. On the other side of them is the beach, a long, curved stretch of smooth sand, interrupted only by the ‘stream’ that has to be crossed to access the far end.

I can’t say where it’s best to cross this stream; conditions vary from day to day depending on the state of the tide and the flow of water. I waded out just inland of the furthest reaching waves. I felt my way across the rounded rocks underfoot, feeling reasonably pleased with my progress. But about three-quarters of the way across, I reached the fastest flow of water, which had also cut the deepest channel. It was probably only a couple of feet deep, but it required great care not to lose my footing. This fast-flowing channel was soon crossed and I hauled myself out, somewhat relieved, on the sand at the other side.

A deserted beach stretched out ahead. I strolled along the water’s edge and, at the far end, cut inland to find the Muliwai Trail, which leads to Waimanu Valley eight miles farther on. The trail is steep and narrow as it zigzags up the cliff. After a short while it breaks into the open and lovely views emerge, back the way I’d come and up the valley where there’s a good view of Hi’ilawe Falls. This was my turnaround point. The return across the stream was easier, knowing what was involved. The hike back up the road to the overlook a steady, sweaty haul, though I was surprised it only took me 10 minutes longer than the descent.

Signs: Hazardous Area

A sign at Mo'okini Heiau

This sign greets visitors to Mo’okini heiau. The heiau dates back to the 11th or 12th Century when it was an important religious site where thousands of human sacrifices were carried out. A hazardous area indeed. I imagine there were many who would happily have risked climbing the walls in those days.

Mauna Loa silverswords bloom and die

A silversword blooms on Mauna Loa.

This is the time of year when silverswords bloom. These plants, members of the sunflower family, are endemic to Hawaii. There are slightly different silverswords growing on Mauna Loa, Mauna Kea and Haleakala on Maui. The plants are very susceptible to root disturbance and the activities of goats, pigs and humans has led to their decline. They’re making a comeback now thanks to fenced enclosures and careful management.

These photos were taken on Mauna Loa a few years back. The flower stalks were about 6 to 8 feet tall. The plants live for up to 30 years, but once they bloom, they die (like the one in the background of the top photo).

In the second photo, the ongoing eruption of Kilauea’s Pu’u O’o vent can be seen.
