A huge fog bank passed through Rangely on Wednesday night last week and left a huge trail of hoarfrost in its wake. Above, tall trees coated with the hoarfrost formed a tunnel of pavement for Rangely residents to drive.
Hoarfrost is formed when the air or fog is so cold that the water/humidity in the air comes in contact with a solid item like trees, leaves, branches and tall grasses, and it freezes. The bright white is caused by the sun shining through the bright snow or frost crystals.
