Clouds Rest viewed from Olmsted Point. Clouds Rest is one of the most massive -- if not the singlemost massive -- granite monoliths in the world. A vast lobe of Mesozoic-era granodiorite magma cooled to rock and was gradually uplifted to its present altitude of 9926 ft. Later, glaciers cut it into its present shape.

The Tree of Eons, Utah. The Tree of Eons is a spectacular geologic sight near the San Rafael Swell in Utah. Here the Tree of Eons is seen under the direct light of midday. Erosion has cut a dendritic "tree" through red, blue, purple and white layers of the Chinle formation. The Tree of Eons is a superb example of dendritic erosion and, to really appreciate its complex fractal-like details, must be observed from above.

Art Seller along La Rive Gauche, the Left Bank, Paris. La Rive Gauch, the Left Bank, is the southern bank of the river Seine in Paris.

Devil's Postpile, a spectacular example of columnar basalt. Once molten and under great pressure underground, the lava that makes up Devil's Postpile cooled evenly and slowly, contracting and fracturing into polygonal-sided columns. The age of the formation is estimated between 100 and 700 thousand years old. Sometime after the basalt columns formed, a glacier passed over the formation, cutting and polishing the tops of the columns. The columns have from three to seven sides, varying because of differences in how quickly portions of the lava cooled.

Canyon X, a spectacular slot canyon near Page, Arizona. Slot canyons are formed when water and wind erode a cut through a (usually sandstone) mesa, producing a very narrow passage that may be as slim as a few feet and a hundred feet or more in height.
