Joints - Joints (fractures) in granite can often form steep-sided gashes that look (from above) like mini-canyons. Granite joints are easily identified, since they tend to be irregularly spaced and occur across bare rock faces. They are easily seen when flying over the Sierra Nevadas of California or Nevada. {read more}.

Scale: Images are taken from an altitude of ~35,000 feet, and so are each ~1 mile across.
