A strangeness of these photographs is this is the middle of February, Chilean summertime.
Force of Nature
Another strangeness, not readily apparent, is the effect of the Coriolis force. Here in the Northern Hemisphere water (any moving mass, really) moving perpendicular to the rotating surface of the earth (a property of water is the surface follows the contour of the solid surface over which it flows) will tend to flow in a clockwise direction. Crossing the equator, in the Southern Hemisphere the tendency reverses, tending to flow to the left, counter-clockwise. With some imagination the effect of the Coriolis force can be seen in the following photograph.
