Brrrrrrrrrrr. An Almost-Wordless Wednesday post.

"This old saying actually has a scientific explanation. It relates to moving high and low surface-pressure weather systems, and the way that the colors in sunlight are scattered differently by dirty and clean atmospheres. This is the explanation of how these phenomena combine to color our sunrises and sunsets." (NOAA link)I read then reread the NOAA page, trying to absorb the explanation of how a low pressure system has a cloudy and cleaner atmosphere causing different scattering of blue vs red light rays, etc. The diagrams helped and I thought I had a grasp on it, right up to the statement:
"A cleaner atmosphere at sunrise or sunset is colored by a mixture of all but the blue colors, giving it a yellowish appearance."What? this week the atmospheric pressure was high, very high, and this is what a sunrise looked like… definitely yellowish. So much for science and folk wisdom - this calls for further study.

"A mile and a half from the mouth of the river lies the Dean River canyon- a narrow, steep section with strong current and many small falls. For an anadromous fish to successfully navigate this section on its way to spawn, it must be not only strong but resilient. Evolution has dictated that there are simply no weak Dean fish- any steelhead in the Dean with less than world-class athletic ability will quickly fall out of the gene pool, losing its battle with the canyon.
Dean River steelhead crush flies. They jump repeatedly. They torch drags. They sprint downriver. They sometimes sprint upriver. They don’t quit, and they often leave shaken anglers wondering what the heck just happened on the end of their line."
