The proximity of the mountains and the high altitude give Boulder Colorado dramatic cloudscapes, with frequent lenticular clouds forming as air moving eastward over the edge of the mountains rises due to the topography. The variety of clouds is quite impressive, especially for someone from Florida where simple puffy cumulus clouds are dominant. On the way home yesterday I saw the sort of colorful roiling clouds that outdid even some of Steven Spielberg’s over-the-top clouds (I’m thinking of Poltergeist, and, of course, Close Encounters of the Third Kind). I managed to get to the house and get my camera just minutes before the hour-long display ended with the setting sun.
