Some high clouds rolling around the Northwest provided a great canvas for Mother Nature to trot out some optical tricks this weekend.
Several astute skywatchers had their cameras ready to capture a brilliant and colorful sun halo, while over in the foothills, some clouds were at just the correct angle to be painted in the colors of the rainbow.
Both of these rainbow phenomenon are caused by ice crystals in those clouds. The crystals refract the sun's light like a prism into the colors of the rainbow.
