One of our friends was hanging out along the South Platte again this afternoon.  Had to shoot pictures into the sun but with the iridescent clouds in the background it looks really cool.

Cloud iridescence is caused by clouds (usually cirrus) that have small water droplets or ice crystals in them causing the light to be diffracted, or spread out. The phenomena is much like the rainbow colors seen with oil in water.

Remember we are always looking for pics of just about anything to add to our monthly slideshow.  Be sure to email or post them so we can add them. Check out this month’s slideshow here.
