It seems to be down in South America somewhere, possibly Chile. Here’s a website that mentions it, but a friend needs its nickname. Anybody have any ideas? Googol only gave me the one site, and it doesn’t say.

Ohhh…it’s a body of water! I thought it was a TV Channel, “All Gabriela, All The Time”, and I’m sitting here wondering, " Gabriela who? Ah, those crazy South Americans…"
Well, I can’t find anything either, but there was a Chilean Nobel laureate for literature whose pen name was “Gabriela Mistral”. Maybe it’s named after her? I have no idea, just a WAG. This website refers to her as “Gaby”, so maybe your friend could call it the “Gaby”?
We thought of Ms. Mistral, and tried Gaby, but it didn’t work. Friend was playing some online game where you had to guess passwords to advance from level to level. This was the only one we couldn’t get. But if you can’t find it, then I will take that as proof that the info does not exist. 
Thanks for trying.
