River Glow | Vantage, WA | 2016
It’s not mystical. The glow from the bottom of the Columbia River is a trick of light — reflection off a sandy bottom or an underwater cliff angled just right. But I’ve visited this spot in all seasons, and even on cloudy days there’s an intriguing shimmer, a shift in the water’s aspect that holds my attention. It makes me wonder: What secret understanding exists among Nature’s forces — geologic, hydrologic, atmospheric, electromagnetic — to create this illuminated mystery?
