Now you see it …

The exterior of the Caltech Submilimeter Observatory before it was decommissioned and removed from Mauna Kea, Hawaii

The exterior of the Caltech Submilimeter Observatory atop Mauna Kea is chock full of triangles, squares, hexagons, curves, lines, etc. You could check it out, except that it’s invisible! Well, it is now, because it was decommissioned in 2015, and last year was dismantled and removed.

The angle of sunrise

Sunrise illuminating one slope of Hualalai volcano, Hawaii.

I was driving up the hill to work, when I noticed the sunrise, over the lower slopes of Hualalai, was illuminating the ridge exactly. It was also creating an angled wedge of shadow on the opposite side of the volcano.

Waiting for the flood

A culvert beneath the old Kohala railway in Hawaii

I’ve always thought this would be a great place to see a flash flood, or at least a little to one side of here. This is a culvert through an embankment of the old Kohala railway. Most of the time, it’s dry as a bone, but when it rains a good deal of water would be funneled through this spot.

These days, round pipes, made of steel or heavy duty plastic, are often used for culverts. This square concrete one looks built to last.

Two views of Hualalai

The second photo shows pretty much the same view, taken on Christmas Day morning. What do you mean, where did it go? It was actually a less cloudy day. The big difference was that the wind was blowing from the southeast, driving vog from the latest eruption of Kilauea in this direction. Vog is volcanic smog and when it’s this thick, it can be quite acrid and you can taste it! It makes life miserable, especially for those with any kind of respiratory ailments.

The vog was bad for two days before the trade winds returned and blew the vog away from this part of the island, allowing the view in the top photo.
