Wyoming's big sky has ample room for this 180-degree rainbow over the Adobe Town rock formations in Red Desert. This seemingly desolate expanse is home to an abundance of life, including antelope, mule deer, and Wyoming's largest herd of wild horses.

A double rainbow plunges into a gorge in Alaska's Denali National Park. Although they appear to exist at a definable point in the sky, a rainbow's position is actually dependent on the location of the observer relative to the sun.

A rainbow spreads over a desert town in northwest Queensland, Australia, after a monsoon soaking. Every year, a climatological flip-flop draws the rainy-season weather down from India and douses this bone-dry land in a phenomenon known locally as "the wet."
