Exploration Stage: Quiet Promenade
From: Ollie Articus
Description: I think that island is also a mirage, but of a more unusual kind. I have seen similar apparitions in the desert, but never in the city! See that upside down carriage? That is a higher level mirage. Let's observe it more closely.
Completed: This is a textbook example of an upper level mirage! It is fascinating to see it so clear and so close. This type of mirage is usually created only at a distance. It is unbelievable.
