Memorial on the coast

A memorial on the Kohala coast.
As is the case in many places, the Big Island is home to a variety of memorials, put in place and maintained by loved ones. Many can be seen by the side of highways, marking the spot where a life ended.

I don’t know the story behind this one, but it’s a beautiful, peaceful spot with its view across the ʻAlenuihāhā Channel to Maui.

James Clerk Maxwell Telescope

I posted here about a visit to the Canada-France-Hawaii-Telescope on Mauna Kea as part of the Kama‘āina Observatory Experience being offered by the island’s observatories. The other observatory visited during that tour was the James Clerk Maxwell Telescope (JCMT).

The JCMT began operation in 1987 and was funded by the United Kingdom, Canada and the Netherlands. However, the United Kingdom decided to improve how it handled its scientific funding and, as a result, early in 2015, the JCMT’s funding efficiently disappeared into deep space and was never seen again. Subesequently, as one of the guides on the tour said, they basically put the telescope on Craigslist and the East Asian Observatory (EAO) picked up the operation.

The telescope is the largest single-dish telescope in the world dedicated to detecting submillimetre radiation. Other telescopes on Mauna Kea operate at different wavelengths so they are complimentary each other rather than in direct competition. And where other telescopes on Mauna Kea are there because of the 300+ nights of clear skies, the JCMT is there for the lack of moisture in the air, which is critical to its operations.

As well as information about the telescope’s operations, the tour included a story about how the steel for telescope’s enclosure had to be sent from England on a small ship after the original freighter broke down. The steel was piled high on deck and was supposed to be headed direct to Hawaii. But the ship’s captain stopped first in Holland to take on a cargo of high explosives! Besides the delay this involved, it also presented problems when the ship arrived at the Panama Canal, for obvious reasons. More delays ensued before the ship disappeared to some port on the Pacific coast to offload the explosives. By the time it arrived in Hawaii, it was so far behind schedule that the penalties accrued for late delivery practically equaled the fee for delivery. However, the ship’s captain, in an apparently canny tactic, waited outside territorial waters and demanded full payment, threatening to dump the steel into the sea if he didn’t get it. This proved to be a bad move! The telescope’s operators took him to court and nailed him for piracy on the high seas. The U.S. Coastguard moved in, took over the ship, and guided it into port of Hilo.

Another story from the telescope’s beginnings concerned the opening ceremony. Several VIPs from the nations operating the telescope turned up, including Prince Philip. When the lever was pulled to start the telescope’s operation, nothing happened. Turned out one of the VIP’s was leaning against an emergency stop button.

Signs: High surf

This is what people think of when they think of Hawaii: golden sand, blue water, and rolling surf at Hapuna beach, often touted as one of the best beaches in the world. Trouble is sometimes the surf gets too big, which is when the lifeguards have to get busy. Not sure the surf in this photo warrants the sign, but even small surf can cause trouble for people unfamiliar with it.

A pigeon, but rock or racing?

I thought this was one of the local rock pigeons hanging out near the cliff edge, but when I got home and looked at the photo, I noticed the bands on its legs. A bit of research on birdwatchingdaily.com revealed that banded pigeons are the same rock pigeon species, but are usually lost racing pigeons.

Turns out there are three racing pigeon clubs on the island as well as several more on the other islands. Unfortunately, I didn’t have a photo with enough information on the band to tell where it might have come from. I saw the same bird a couple more times without getting a better view, and then it was gone.

I don’t know if it suddenly remembered its way home or simply ingratiated its way into the local rock pigeon flock.

Kohala Girls’ School

The Kohala Girls’ School was founded in 1874 by Ellen and Elias Bond, missionaries who came to the Big Island from Maine in 1840. It remained in operation until 1955. Since then the buildings saw only occasional use, but they are currently being renovated as part of the Grace Learning Center, an educational program of the Kohala Institute.

The land managed by the Kohala Institute is called ’Iole and is one of Big Island’s the last intact ahupua’a. An ahupua’a was a land division that stretched from the sea to the mountains, giving those who lived there access to everything they needed for self sufficiency.
