So, what happens when you come across a rainbow at sunset? Apparently you get a firebow! This rare phenomenon looks as if the sun itself has relocated to the surface of Planet Earth to light up the evening with spectacular style. . . All of the moisture in the atmosphere erupts into a brilliant golden glow as the firebow rings the perimeter with an arc of color. I’m going to put this one down as once-in-a-lifetime experience. Words cannot describe just how special this moment was. Why is the bottom of the rainbow cut off you ask? That’s actually the shadow of Pikes Peak clipping off the last rays of sunset on this fine summer evening.
