"The lost river: a curious case of water biome in Paris"

#PokemonGO: Hi everyone! First, please forgive me if my english is a bit weird or academic, i'm french as you can see above and only learnt it at school.I wanted to tell you about a strange spawn pattern I found close to my place in Paris recently. I walk on the same street everyday twice a day, and I noticed a few month ago that one Pokestop in particular would always have a Magikarp around it, whereas the biome in the neighborhood is the boring Pidgey/Rattata stuff that we get here in Paris.At first, I thought it was just RNG or something, but, curiously enough, it only spawned Magikarps and nothing else, contrary to a nest or a Pokestop with rare spawns, as you sometimes get.I didn't really think about it until recently. Last Sunday, since I had some time ahead of me, I tried to map the area of Magikarp spawn, and I was quite surprised to find out it made sort of a broken line across the 5th and 13h districts of Paris. Just to confirm, I cheated a bit and went to a french tracker, as you can see on the picture below:http://ift.tt/2opzrGm this, this sort of a line reminded me of something: if you ever visited Paris, you do know that the Seine river is flowing through the city. However, there used to be a second smaller river, flowing across the left side of the Seine: the Bièvre river. If you speak french ever so slightly, you can read Wikipedia about it, it's quite well written (http://ift.tt/2gN6CA1, the english article is a bit crappy), but to make a long story short: this river was covered during the 19th century and now flows underground. As you can see on the right of the picture linked above, the former river and the Magikarp spawn pattern seem to fit quite nicely.Although it will certainly not give you any XP or help you get a Dragonite, I thought this observation was quite nice when it came to understanding how biomes were generated: there has to be some automatic process in that, considering the huge area covered by Pokemon Go. However, this type of pattern strongly suggests that Niantic does modify biomes in quite an intricate and clever way, to fit to the history of a certain place.I hope you found that interesting. If you live in Europe or in an old enough city anywhere else, maybe you could find something similar where you live! via /r/TheSilphRoad http://ift.tt/2o6vpAY
