On my way I saw this scene: a combination of fig.1 and fig.2, except those high hills.
Then I am happy to find out it is related to "wizard of Oz", because most of the rainbow images are only half of it shows. The rainbow formed a giant door like Gateway Arch in St.Louis, I entered this door in right,straight angle, what a lucky omen.
