During a recent swim, I was lucky enough to see this gorgeous double rainbow. I took several photos and this one is actually a composite. In the best rainbow photo the water looked a bit flat, but in photos that gave a glimpse below the water’s surface the rainbow wasn’t as good. So I combined the best of both and it came out pretty good I think, especially given my rudimentary skills in my Photoshop Elements.
Turtles are creatures of the water. The only reason they have to venture ashore is to lay eggs, but in Hawaii, green turtles like to find a beach and spend a lazy day basking in the sunshine. This helps them conserve energy and keeps them safe from sharks.
On the Big Island there are a number of places where turtles are frequently seen on shore. One of them is Punalu’u Beach Park, on the Kau coast, which has a lovely black sand beach ideal for getting a bit of rest. Well, it would be ideal except for that most annoying and obtuse of creatures, the human.
There are apparently large numbers of people who don’t know how to read the numerous signs telling them to keep their distance from the turtles. There are a fair number of people who think the world would be a better place if only there existed a photo of them sitting beside or on top of a turtle.
These days, park staff or volunteers tape off the area where the turtles are resting. This seems to help. The bottom photo was taken from behind the tape with a moderate telephoto lens so it’s not like anyone’s being deprived of getting a good view.

This photo shows the two main types of lava found on the Big Island. On the left is pahoehoe lava and to the right, a’a lava. They’re noticeably different. Pahoehoe lava is typically rounded and smoother, and the height of the flow is quite modest. A’a flows are characterized by a rough, clinker surface and the flow height is greater. Both types of lava can be produced by the same eruption and even in the same flow, depending on conditions.
Pahoehoe flows occur when lava is hot and fluid. Typically, pahoehoe flows result from an eruption that outputs lava at a lower rate, has a lower flow rate and a slower moving flow front. The slower movement of the flow allows a skin to form on the surface and this insulates the lava within. The flow is actually made up of a large number of ‘toes.’ Each toe flows for a short time, a matter of minutes. When it stops, the lava inside causes the toe to expand until the skin cracks and releases a new toe.
A’a flows are more viscous, but with a higher flow rate and faster flow front. The lava in the center of the flow is very dense with a layer of rough clinker on top. As the flow advances, the front tumbles over itself breaking into more rough pieces.
It’s easy to see from the photo that walking is much easier over pahoehoe lava than a’a lava. That’s when it’s cooled of course. When it’s red hot and flowing, it’s best not to get too close.
This flow was on the north side of Mauna Loa, looking across to Mauna Kea.

Rainbow Falls are located in Wailuku River State Park, in Hilo. They get their name from the fact that, in the mornings, rainbows often form in the mist from the falls (above).
Center, someone left an offering, possibly to Hina, mother of the demigod Maui, who is said to have lived in the cave behind the falls.
And below, someone who has inadvertently walked past the 83,000 ‘Danger’ and ‘Warning’ signs to wander around at the top of the falls. Flash floods occur often and people die here every year.
I’m posting this photo in response to this week’s Sunday Stills challenge on the theme of ‘Friend’ (see more responses here), though it would be equally suitable for next week’s ‘Lazy Days.’
Monk seals are solitary animals, the main exception being the six weeks or so a mother spends with her new pup, teaching it the tricks of the trade, before leaving it to fend for itself. But for a three month period in late 2016, these two monk seals spent a lot of time together.
The top seal is I05, a male, affectionately known as Igor. He’s a Big Island seal and appears to spend his time on the Kohala and Kona coast. The other is B00, a female, affectionately known as Boo. She was born in Kauai and had previously been seen on Molokai and Maui, but now appears to spend much of her time on the Kona coast. Whereas not too much had been known about B00, I05 was regularly seen and was a notorious loner. So his ongoing liaison was quite out of character.
They seemed very relaxed and content in each other’s company, and here are resting ashore, as monk seals do, before heading back into the water to feed.
No, it’s not the circus come to town. These tents are for a more macabre purpose, the termination of termites.
As in most warm climates, termites are a problem here. Houses, especially older ones, are easily colonized. Without treatment, the occupying termites will consume wood from the inside, leaving a thin membrane as protection. Infested wood might look fine, but a gentle push on the surface will go right through two or three layers of paint to the termites’ cavern inside.
Besides leaning against a wall and going right through, a prime indicator of termites is small mounds of little round pellets below a pinprick hole in a wall or piece of furniture. These are termite fecal pellets, which the worker termites clear out of the nest from time to time.
Another indicator of the presence of termites is to turn a light on and find a horde of them flying around the room. Around here, May is the prime time for this activity. These flying termites are fertile males and females, leaving the nest they grew up in to find a place of their own and start a new colony.
As unpleasant as it is to find a room full of flying termites, it’s even worse to wake up and see countertops littered with discarded wings, a sure sign that these fertile termites have moved in to a new spot.
So tenting for termites is common practice here. The structure is covered with nylon sheeting until it is completely sealed and then a fumigant is pumped in. The tent usually remains on overnight. After the tent is removed, the house has to sit empty a while for the gas to dissipate. It’s not wise to go back in too early or one could find oneself joining the termites. Typically it can be two or three days before a home can be reoccupied.
Tenting for termites is effective but it has downsides. It works for drywood termites, but not subterranean termites since they live outside the house and just dine inside. There are also environmental concerns about the process. And while fumigation works, there’s no guarantee that a new colony of termites won’t move in just as soon as the gas has cleared.
Actually, it would take more than a vowel for me to figure out what was writ upon this old blockhouse wall.
