My sister-in-law took these pictures at Olympic National Forest in Washington this weekend. She knew that the "weather geek" in me would really dig the pics.
Hoarfrost is different from "normal" frost because when it forms, it goes from water vapor straight to ice crystals (like snow). "Normal" frost goes from water vapor, to water droplets, to ice.... Also called "rime" frost. Here are the cool pics!
Thanks for the pictures Ami!!!
