Trying to recall a science fiction short story which begins with the protagonist being asked to join a husband and wife team on a trip to South America (IIRC) to investigate a mysterious phenomenon (I think it was a constant, never-ending wind) in some high mountain valley type of locality. The strange phenomenon is discovered to be caused by some kind of alien artifact, I think a miniature black hole or space warp may have been involved.
I am pretty confident this story isn't too old, and that I read it in a "Best SF of the Year" anthology.
