Cone Clouds

Reminiscent of a Marvin Cone painting, these cumulonimbus calvus clouds billow in the distant north sky along US Highway 20 around 4:50 PM, Sunday, June 19, 2011. This position was located at the River Forest Road exit (Exit 70) at Evansdale, Iowa, less than mile east of Waterloo. Cone (1891-1965), a Cedar Rapids, Iowa native and friend of artist Grant Wood, was well known for his oil paintings of billowing clouds.
