This shot looks straight down on a corral of a few hundred cattle being gathered for their vaccinations. The animals normally roam free across thousands of acres but when its time to see the doctor the gauchos (Argentine cowboys) need to gather them up on horse back and bring them into the corrals to then pass through "la manga", a wooden structure that funnels the cows until they are walking through in a single file line, to get their shots. You can see the on upper right hand side of the image there guachos' horses wait outside the corral.
Looking straight ahead from the previous photo, you can connect the canals up all the way into the lagoon in the distance.
Now you can see the teardrop shaped lagoon from the image above out in the distance of this image. Capturing both the Atlantic ocean and the lagoon you can see how the farmland backs right up to the sand dunes and beach.
