Blue moon illuminates the Rowena loops
The August 31, 2012, blue moon illuminates a curve on the Columbia River Historic Highway near Rowena Crest in the Columbia River Gorge, Oregon. The Rowena curves are a set of hairpin turns that zigzag their way from riverside to the spectacular viewpoint Rowena Crest at 700 feet above. There are two definitions for a blue moon. The easy, modern one is the second full moon in a month. The traditional definition is the third full moon in a season that has four full moons. A season (3 months) usually has only three full moons. Of course, it is still the night sky that is blue while the moon remains golden white.
