At first, you may think this is simply film panning over a delightful lake.
Be that as it may, soon you understand the staggering waters in Serra de Estrela in Portugal shroud an unusual mystery.
Taped by an automaton, you can see a tremendous gap in the waterway, with dilute pouring underneath.
The gap appears like a vortex, expending the waters around it.
In any case, lamentably this isn’t a gateway into another measurement.
It’s a dam worked in 1955 that is in charge of the water redirection between Ribeira das Naves to Bayou Lagoon Long.
There you have it. Still delightful to take a look at it, however.
