Last weekend my husband and I went flying over the Rockies from Denver to Monte Vista. We flew in a plane piloted by a friend and got to look at turning golden Aspen leaves from far above. I am always astounded by the color schemes of nature. We looked down at mustard gold, deep forest green, inky navy blues and burst out into the sandy golden desert of the San Luis valley marked by irrigation rondelles.
Always when I am high above the world looking at the clouds I think of Georgia O'Keefes interpretation of clouds which she saw while traveling during the 60's. This is "Sky Above Clouds IV" by Georgia O'Keefe and I believe it can be seen at the Chicago Art Institute.
Another cloud image which makes me smile is painted in pastel by my longtime friend, artist, Eugenie Torgerson. entitled "One Perfect Day". Checkout: blog.eugenietorgerson.com.
Leonardo Da Vinci said that clouds were " bodies without surface"
If clouds are bodies without surface then mountains are bodies filled with surface.
I also discovered for cloud lovers this site which you can explore for poetry, visuals et al. http://www.cloudappreciationsociety.org
