Spatial Variability of Snow Chemistry in a Seasonal Snowpack, Southeastern Wyoming

This study examined the spatial and temporal variability of chemistry in the seasonal snowpack of the Glacier Lakes catchments in southeastern Wyoming. Snow board data revealed high pH snows (mean pH> 5.0) had higher mean SO4^2- concentrations than low pH snows (11.8 μeq L-1 versus 8.5 μeg L- 1) but lower mean NO3- concentrations (8.2 μeq L-1 versus 10.0 μeg L-1). The high pH snows were also deeper and had higher mean values for Ca^2+, Na^+, and Mg^2+, but lower mean conductivity and density. Different source areas may explain the differences between these two types of snow.hydrology collectio
