Alpenglow
Etymology
A partial translation of German "Alpenglühen" ("Alps-glowing"), combining "Alpen" (the Alps) with English "glow." It names the phenomenon in which sunlight, scattered by the atmosphere, illuminates mountains from a sun you can no longer see directly.
noun · /AL-pen-gloh/
The rosy or reddish light that bathes mountains just before sunrise or after sunset.
What it names
A specific word for that brief pink fire on high peaks — the diffuse, sourceless glow that lingers when the sun itself is already below the horizon.
Example
They reached the summit at dusk just as the alpenglow turned the whole range the color of a peach.
Related idea
Not the same as a sunset, which is the sun’s own colored descent; alpenglow is the afterlight it leaves on high surfaces once it has already dropped out of sight.
