On January 4, I commented in a post that Lake Nahuel Huapi had changed its color, from its usual deep navy blue color to a pale turquoise hue. Everybody was wondering what was the cause. Some had suggested that it was due to an earthquake in Chile that had shaken up sediment from the lake bed.
Well, the riddle has been solved: the cause seems to have been an inflow of "sedimentsthat the lake received from the upper basins of the rivers and streams that flow into that sector due to last week's intense rainfall"[1].
