Extreme

When
we think of a mirage, we usually think of a hot desert. In the arctic,
though, the thermal layering of the cold air causes a similar effect.
The effect is the opposite of a heat mirage though. Here, you can
see that the mountain looks to be up-side down and mushroom shaped. |

Here.
the bottom mountain looks to have a twin growing out of the top. This
is simply an optical illusion |

Sundogs
are caused by the light of the sun being reflected off of ice crystals
in the atmosphere. this causes a ring around the sun with rainbow
colors at either side . |
