Short summary
This study observes the movement of snow water equivalence (SWE) during mid-winter surface melt and spring snowmelt periods. We observed that the south-facing slope that experienced mid-winter surface melt events showed meltwater flowing downslope through the snow. The north-facing slope saw a similar redistribution of meltwater during the spring snowmelt period.
