Dust on Snow

April 8, 2014--Snowpack dust is trending upward (Durango Herald)

The good news is that this year’s dust storms have not deposited as much grit on this area’s snowpack as last year’s. The bad news: Last year “broke the sound barrier” for dust deposits, and this year is continuing a decade-long increase. That’s according to the latest measurements by the Center for Snow and Avalanche Studies.

Dusty air blowing in from the drought-parched Southwest is subtly changing the color of the snow on the Rocky Mountains, affecting water supplies for millions of people in more than half a dozen states. The dust-darkened snow, tinged the color of cinnamon, absorbs more sun and melts earlier in the year—a problem for fa

Even before a series of intense dust storms coated the Rocky Mountain snowpack in 2009 and 2010, scientists had calculated that the dust speeds the spring meltdown and reduces runoff in the Colorado River Basin by as much as 5 percent, based on data gathered between 2005 and 2008.

Significant dust storms the past few years have had a big impact on the timing of snowmelt in the Colorado Rockies, but scientists haven’t been able to say for certain if those events are becoming more frequent.

Winter finally arrived in the Colorado high country, but not until the second week of December, after a November that saw average temps run an eye-popping 7 degrees above average.While the timing is a little unusual, it’s not unprecedented, and after two years in a row of lackluster early season snowfall, many people want to know if global warming is a factor in the changes.
