The part of the world I’m in is flat. From horizon to horizon, there is hardly a perceptible elevation change. No hills, mountains, bluffs… nothing. Just dirt and small bushes. Consequently, the sunset is far more red than it is in Vegas due to the attenuation of the higher frequencies of light in the atmosphere. The longer wavelength of the low end of the visible spectrum makes it through while the higher energy blues and such get filtered out. So on a really clear day you get absolutely spectacular sunsets. The same sort of sunset is visible at any beach, as well, but these are really my first experience with such a red sunset being that I’m from Vegas… at the bottom of a valley surrounded by peaks at 10,000’+.
