Plains sunrise produces a glowing orange band plus amethyst-lit mountains

Evidence

You can form no idea of what the glory on the Plains is just before sunrise. Like the afterglow, for a great height above the horizon there is a shaded band of the most intense and glowing orange, while the mountains which reflect the yet unrisen sun have the purple light of amethysts. — Isabella L. Bird, A Lady’s Life in the Rocky Mountains, 215
