Each year, during part of February, if the lighting conditions are just right, Horsetail falls, a small seasonal waterfall in Yosemite National Park, transforms color for a fleeting moment, turning gold and then appearing as if lava were flowing down the side of El Captain.

Eucalyptus deglupta is a tall tree, commonly known as the Rainbow Eucalyptus, the Mindanao Gum, or the Rainbow Gum. It is the only Eucalyptus species found naturally in the Northern Hemisphere. Its natural distribution spans New Britain, New Guinea, Ceram, Sulawesi and Mindanao. The tree is cultivated around the world, mainly for pulpwood used in making paper. It is the dominant species used for pulpwood plantations in Philippines.
This tree is also grown for ornamental purposes, due to the showy multi-coloured streaks that cover the trunk. Patches of outer bark are shed annually at different times, showing the bright-green inner bark. This then darkens and matures to give blue, purple, orange and then maroon tones. - Wikipedia
