It’s not all hulking mass and destructive power though. Some of nature’s most beautiful and delicate structures are made of ice. Upper atmospheric particles dance in the air refracting the light of the sun or the moon into eerie circles and bows. Hoar frost delicately grows from moisture sucked from snow on frigid nights. Each feathery tip inching outwards, silently waiting for even a slight breeze to shatter its pristine form.
Ice can also bend light. When photons of light hit aerated ice, the spectrum of light bounces around in this loose structure and is sent back at us in the full spectrum–white. But when ice is purer with less air, the long waves on the red spectrum are absorbed and only the blue (and in smaller amounts green and violet) short wave light particles are reflected, which is making the ice appear blue to the human eye. The deeper you peer into a crevasse, the more red light is absorbed and a deeper blue is created making the ice appear to be glowing from the inside.
