What Is Rime Ice?

During the winter months, you will often see white on mountaintops or up just one side of a mountain. You may think it's snow, but it could be rime ice formed when water droplets in clouds or fog freeze to the trees. Often, the rime ice forms just on the windward (wind-facing) slope of the mountain as clouds sweep over the ridge.

Wind will work with the moisture and freezing temperatures to form some beautiful scenes and sculptures. In the photo on the right, you can certainly tell which way the wind is blowing! It creates a winter wonderland for hiking. Many times, the rime ice will coat the trees and the ground is dry. But when rime ice is combined with snow cover, it creates a breathtaking walk in the higher elevations near Asheville.

We took these images at Craggy Gardens. Located on the Blue Ridge Parkway, the Craggy section of the Parkway is closed much of the winter.

The west side of Craggy Pinnacle is covered with rime ice.

Some fall leaves are still hanging on in the 20 degree weather.

Wind direction is evident as the clouds sweep up the mountain side and deposit moisture.
