Reader photo: Snow ghost
Donald Sewell came across this ice-covered tree on Mount Spokane, Jan. 30.
Called a snow ghost, this tree is covered in ice called rime. The ghostly shapes are formed when clouds and fog made of suspended liquid water droplets collide with the trees. While the water remains liquid in the cloud, as soon as it collides with an object – like a tree – it freezes.
These droplets slowly add up creating thick layers of ice.
