The Center for Snow and Avalanche Studies (CSAS) is home to “CODOS”, the Colorado Dust-on-Snow program, an applied science effort on behalf of Colorado and regional water management agencies.   CSAS operates the Senator Beck Basin study area at Red Mountain Pass as the primary sentry site for the CODOS program. With direct funding from stakeholders, CSAS monitors the presence/absence of dust layers at 11 mountain pass locations throughout Colorado. Using those observations, data from nearby Snotel sites, and weather forecasts, the CODOS program issues a series of “Update” analyses of how dust-on-snow is likely to influence snowmelt timing and rates during the runoff season.
