Mountaintops are sometimes known to discharge electricity into the atmosphere, emitting
a silent barrage of bright flashes that fade into a glow across the sky. This phenomenon
is seen in the mountains of South America, the Alps, and the Rockies. The glow that the
Andes glow emits spreads high into the sky, across mountain peaks, and for distances as
large as three hundred miles.
The rays of electricity, which may have two distinct flashes, are bright yellow or
orange in color, with an occasional green or pink streamer. As the glow develops, the
different colors disappear and are substituted by white or pale yellow.
The glow can be spectacularly fantastic if it is accompanied by an earthquake’s repeated
electrical discharges. During a giant quake that hit Chile in 1906, witnesses reported
that the entire sky seemed to be on fire.
