green on blue (weekly photo challenge: up)

Earth Day dawned cold after a cloudless night.  As the sun warmed the air and earth, I ventured out for a walk in my neighborhood with my husband Creighton, and beagle Josie.  There was one dab of a white cloud in the sky looking like it might be lost and wondering where all the other clouds had gone.  Walking under a tall Aspen tree, I looked up to see its leaves framed against the bright blue sky.  As long as I can remember I have loved the sight of spring green leaves upon the background of blue sky.  In an earlier post I noted that the green in plants is created by photosynthesis; the process in which light is absorbed by plant proteins that contain chlorophyll pigments.  And what makes the sky blue?  Molecules in the air that scatter blue light from the sun more than they scatter red light.  Here are some of the images I captured of green on blue.

    The green on blue pics are beautiful!
    We’re home — to see Claire in Thoroughly Modern Millie (at Camas HS), to visit a granddaughter and her 3 girls who are here from VA, and then to cruise Alaska.
    Maybe plan a get-together in June???
