Outwash
Meltwater from mighty Vatnajökull glacier has carried ground rock down through the mountains. Over time, this has been deposited in deltas where the river spreads and the current slows.
The result is these beautiful braided sandbanks, cut and recut by changing water volume, piled up in the quiet times and then swept away by jökulhlaup.
Early October, 4pm: Lónsöræfi in south-eastern Iceland.
