El Capitan
El Capitan, also known as El Cap, is a vertical rock formation in Yosemite National Park, located on the north side of Yosemite Valley, near its western end. The granite monolith is about 3,000 feet from base to summit along its tallest face, and is a popular objective for rock climbers. 
Horsetail fall is a seasonal waterfall that flows in the winter and early spring. The fall occurs on the east side of El Capitan. Around the second week of February, the setting sun hits Horsetail Fall at just the right angle to illuminate the upper reaches of the waterfall.
Can only be seen at certain time of year
