I had a hard time believing this was real, but this is the Rainbow Eucalyptus (Hawaii, U.) which grows in the South-Pacific area. The amazing color variations are naturally formed when the tree sheds bits of its bark as it grows.
Oneonta Gorge, Oregon is in the Columbia River Gorge with a unique set of aquatic and woodland plants. The ferns and moss make the walls look like a fairy tale, and visitors can walk through the creek on a warm summer day.
