Colorado Dust-on-Snow (CODOS)
With direct funding support from stakeholders, CODOS monitors the presence/absence of dust layers at 11 mountain pass locations throughout Colorado.

With those data, data from nearby Snotel sites, and weather forecasts, CODOS provides its funders with a series of “Update” analyses of how dust-on-snow is likely to influence snowmelt timing and rates during the snowmelt runoff season.

March 26, 2012:
Dust event D6 underway in western San Juan Mountains

Greetings from Silverton on Monday afternoon, March 26 -

Strong SSW'ly winds are now delivering another dust storm to the western San Juan Mountains and likely well beyond into the Colorado Mountains.  This event D6-WY2012 is arriving here dry, without precipitation, and falling directly onto largely exposed and merged layers D5/D4 at the snowpack surface.  These S and SW winds are expected to sustain into this evening but wane by morning.  We will be in the field tomorrow in Senator Beck Basin and report thereafter.

You can view our current Putney Study Plot wind data, in either tabular form or as a 1-, 12-, or 24-hour wind rose,  at https://snowstudies.org/current1.html

USGS's Colorado Plateau web cams are also available for Abajo Peak, Mesa Verde, and Canyonlands National Park.

More soon,
Chris
