Albedo (broad band) at Swamp Angel Study Plot was 0.42 (42% reflectance) at mid-day on May 21; albedo values fell as low as 0.35 during the spring of 2013, with considerably more dust mass in the snowpack.

Another example of differential melt rates between clean snow – the clean snow ‘donut’ roller from Storm #24 – and dirty snow. The Storm #24 snow is still visible on the white, north-facing side of this gully, where the roller originated, whereas all of Storm #24 was ablated from the bottom and south-facing side of the gully. This white ‘donut’ has survived over a week of sunshine.

Andrew Temple approaching the Senator Beck Study Plot, at 12,180’. Dust layer D8 was widespread and is clearly evident on the snow surface to the right of the tower. The very dirty patches below the distant ridgeline are merged D3-D8 dust. Much of the dust in the alpine terrain in Senator Beck Basin is still buried underneath Storm #23 and #24 snow but dust layer D8 is accelerating the ablation of that cleaner snow.

On south and southeast aspects in Senator Beck Basin, absorption of solar energy in dust layer D8 produced enough melt to initiate extensive “wet-loose” avalanches scouring down to the underlying merged D3-7 dust layer.
