A brisk cold front blew through the Outer Cape late this afternoon, with dark clouds and heavy rain. As the front went past, just before sunset, the sky opened up on the western horizon, out over Cape Cod Bay. I went out to have a look.
The first thing I saw was a magnificent double rainbow. The sun was low in the sky, and so the rainbow made a mighty arc that seemed to stretch most of the way to the zenith. (No comment from you science geeks; I already know that the primary arc of a rainbow is at 42° from the antisolar point.) It was so big, though, that I couldn’t get it all at once with the camera in my phone.
My first stop was Powers Landing, on Wellfleet Harbor. Here’s the center of that rainbow’s arc:
Here’s the left side, looking west along Mayo Beach:
And the right side, looking south over the harbor:
Best rainbow I’ve ever seen, I think.
It was almost sunset, so I high-tailed it over to my favorite vantage point, a high bluff that faces west across Cape Cod Bay. (We call the place “Avalon”.)
When you get to the top of the bluff the trail goes south for a bit, parallel to the water’s edge.
Here’s the same shot from close to the ground:
Once I’d reached the lookout I just stood there taking in the constantly changing light. Some more shots:
Finally, the sun set, and it was time to go.
What a beautiful place this is.
