The Numbers Game #26

Sunrise from the road to Mauna Loa Observatory, now no longer accessible since the 2022 eruption.

The idea of The Numbers Game is to enter a number into the search bar of your computer and then post a selection of the photos that turn up. This week’s number is 147. Captions are on the photos. You can see more responses here.

Mauna Kea Silverswords

Next door the Mauna Kea Visitor Center is an enclosed area where Mauna Kea Silverswords (Argyroxiphium sandwicense subsp. sandwicense) grow. These silverswords are closely related to species found on Mauna Loa and Haleakala on Maui. All silverswords are at risk of extinction. The reasons are the usual suspects: humans, feral sheep and goats, climate change. They also suffer from a lack of genetic diversity. The current burgeoning population of more than 8,000 has been produced from only six wild plants.

Silverswords can grow for 30 years or more, but once they bloom, they die. I haven’t seen a Mauna Kea Silversword blooming, but I was lucky enough to see Mauna Loa Silverswords blooming not long after I moved to the island (here). The second photo shows one of those plants in bloom. It was over six feet tall!

Clouds in the Saddle

Clouds in the saddle on the Big Island, Hawaii

The Big Island’s weather is greatly influenced by northeast trade winds blowing up against Mauna Kea and Mauna Loa and dumping generous quantities of rain on the wet east side. Not much of this moisture reaches the much drier west side.

On a recent hiking trip to the saddle between Mauna Kea and Mauna Loa, I saw a visual example of what goes on. Cresting a hill, I saw a bank of cloud rolling in from the east. My hike was somewhere under that cloud. When I got closer to that wall of cloud, I could see it fading as it pushed to the west.

My hike started under gray skies, with some light rain, but on this day, the clouds did not keep building. Instead, they burned off somewhat so that it was dry and quite hot by the time I returned to my car, such is the fickle nature of Big Island weather.

Planes over Hapuna

Pohakuloa Training Area is a large military training area, occupying more than 100,000 acres on the lower slopes of Mauna Loa. Units from all around the country come here for training.

Recently, a series of jump operations were held over several days. As part of these exercises, formations of large aircraft were flying around the area, including over Hapuna, which is where I work.

On this day, the first flight went by while I was occupied, but when the next one came into view, I was ready with my camera. There were around 15 aircraft rumbling overhead at a relatively low altitude and I was pleased that their track took them past the half moon hanging in the sky.

View of Mauna Kea and Mauna Loa

A View of Mauna Kea and Mauna Loa from Kohala Mountain Road in hawaii

There’s still a bit of snow on top of both Mauna Loa and Mauna Kea. Every time it looks like it’s going to disappear, a new dusting bolsters the coverage.

This view is from Kohala Mountain Road. The dark strip snaking through the center of the photo is housing alongside Kawaihae Road, which goes down to the coast. These houses are part of the town of Waimea, which sits in the saddle between Mauna Kea and Kohala Mountain. This part of Waimea is known as the dryside because it receives significantly less rainfall than areas on the east side of the saddle, which is known, correctly, as the wetside.

Road closed

This week’s Sunday Stills challenge theme is ‘Roads, Paths, and Streets.’ See more responses here.

After a recent hike off Saddle Road, I had time to take a drive up one of my favorite roads on the island, which leads to the Mauna Loa Observatory. Well, it used to; it doesn’t get there anymore. That’s because a flow from last fall’s eruption of Mauna Loa crossed the road a few miles short of its destination. I was curious to see what the scene looked like now.

The cloudy skies added some atmosphere to the drive which was, as always, a lot of fun. It’s a winding one lane road, so even though there’s little traffic, one has to pay attention. Any distraction could result in driving off the road into the inhospitable lava fields bordering it.

I confess, my secret hope was that, when I arrived at the flow, there would be a sign saying ‘Road Closed.’ Alas, that was not the case. Clearly, the Department of Transportation figured the seven foot high wall of lava conveyed the message well enough on its own. The only sign there warned against walking on the new flow. I didn’t need that warning. This is a’a lava which is really hard to walk on anyway, and in a new flow it could be quite unstable and even harbor pockets where one could fall through into still hot lava! Still, I’m sure some folks have clambered up there just because it’s there.

I took a few photos, then turned around and headed back down, not least because it was damp, windy and I was freezing, which is not why anyone comes to, or lives in, Hawaii.

The HISEAS dome on the slopes of Mauna Loa

On the drive down, I got a good view of the HI-SEAS (Hawai’i Space Exploration Analog and Simulation) dome. This is where teams of volunteers do research for what it would be like to be living on the Moon or Mars. I’m not sure if it’s in use since the COVID shutdown, but at least it survived the last eruption.

Farther down, the land seemed to be steaming, but in the saddle between Mauna Kea and Mauna Loa, the weather often seems to be part of the landscape.

And the views, which change with every twist in the road, are strange and stunning and wonderful. It may not be possible currently to reach the end of the road, but it’s still a great drive.
