HYAK, Wash. -- Those who headed for the higher elevations of the Cascades during a somewhat foggy stretch of weather in Western Washington in late January were treated to quite the sight: A "fog waterfall."
"We were up skiing at Alpental," said Seth Yates. "Took the chair lift out of the clouds and into the sun and saw this 'fog waterfall' from the top."
It might look like water, but the wind blows the top layer of the fog along and over the mountain tops. The fog gradually disappears as it drops over the mountains because air will become warmer and drier as it sinks, pushing it away from condensation levels.
