Red Beach, Peru
PhotographerSamuele Gasparini; Summary Authors: Samuele Gasparini, Jim Foster

Shown above is Red Beach, part of the Paracas National Reserve, on the barren shores of the Pacific Ocean in Peru. The red coloration of the beach is attributed to pink granodiorite that has eroded out of the nearby cliffs of Punta Santa Maria by wave action, forming a reddish pebble-sand mix. The carmine color of the beach contrasts with the tans and browns of the adjacent coastal cliffs. Over 200 migratory bird species and approximately 3 dozen species of land and marine mammals are found in the Paracas Reserve. Photo taken on August 9, 2011.

On top of Mt. Whitney

Mt. Whitney, the highest peak in the Sierra Nevada Mountain Range, appears in this spectacular photo from the US National Park Service. 

Mt. Whitney is the remnant of a giant magmatic body produced about 80 million years ago. At the time, an oceanic plate called the Farallon plate was sinking beneath the state of California and the U.S. West Coast. As this plate entered the mantle and was heated, water and other fluids trapped in it were released. They migrated upward, causing the hot mantle rocks above to melt.

Those magmas migrated upward into the crust, building a classic volcanic arc. At some places in the Sierra Nevada, rocks that erupted at Earth’s surface are still preserved, but in the southern part of the mountains, the deep roots of the magma system are exposed. 

The Mt. Whitney Pluton is a granodiorite; not quite as silica rich as a granite but still a fairly common rock type from subduction zones. Mt. Whitney is the remnant of a giant magma chamber, a magma body over 50 kilometers long. It likely fed hundreds of volcanic eruptions when it was active. Today it is a giant piece of rock with tightly interlocking crystals, a product of slow cooling within the crust. The fractures you see that define the shape are called joints: fractures that tend to open in rocks when they come up to the surface and pressure on them is released.

Mt. Whitney is named for California’s first state geologist, Josiah Dwight Whitney.

Granite Statue of Tutankhamun

18th Dynasty

c.1350 BC

Upper section of a granodiorite figure of Tutankhamun: wearing a royal ‘nemes’ headcloth, false beard, beaded broad collar, and elaborately pleated kilt, steps forward to present a chest-high pillar that once tapered toward the statue base (now lost). The three exposed surfaces of the pillar are decorated with low raised relief depicting lotus blossoms, bunches of grapes, pomegranates, sheaves of grain, and clutches of bagged ducks hung by their feet. An adjoining fragment from the lower part of the statue preserves the umbels of papyrus plants that “grew” from the base on the proper left side of the sculpture. This may be a depiction of the pharaoh in the guise of the god Hapi, who embodied the Nile in flood. The back-pillar is inscribed.

Statue of Lady Sennuwy (Nubia/Kush/ Modern day Sudan)
Kemet
Middle Kingdom, Dynasty 12, reign of Senwosret I
1971–1926 B.C.

This elegant seated statue of Lady Sennuwy of Asyut is one of the most superbly carved and beautifully proportioned sculptures from the Middle Kingdom. The unknown artist shaped and polished the hard, gray granodiorite with extraordinary skill, suggesting that he was trained in a royal workshop. He has portrayed Sennuwy as a slender, graceful young woman, dressed in the tightly fitting sheath dress that was fashionable at the time. The carefully modeled planes of the face, framed by a long, thick, striated wig, convey a serene confidence and timeless beauty. Such idealized, youthful, and placid images characterize the first half of Dynasty 12 and hark back to the art of the Old Kingdom. Sennuwy sits poised and attentive on a solid, blocklike chair, with her left hand resting flat on her lap and her right hand holding a lotus blossom, a symbol of rebirth. Inscribed on the sides and base of the chair are hieroglyphic texts declaring that she is venerated in the presence of Osiris and other deities associated with the afterlife.

Sennuwy was the wife of a powerful provincial governor, Djefaihapi of Asyut, whose rock-cut tomb is the largest nonroyal tomb of the Middle Kingdom. Clearly, the couple had access to the finest artists and materials available. It is likely that this statue, along with a similar sculpture of Djefaihapi, was originally set up in the tomb chapel, although they may also have stood in a sanctuary. Both statues were discovered, however, far to the south at Kerma in Nubia, where they had been buried in the royal tumulus of a Nubian king who lived generations after Sennuwy’s death. They must have been removed from their original location and exported to Nubia some three hundred years after they were made. Exactly how, why, and when these pieces of sculpture, along with numerous other Egyptian statues, found their way to Kerma, however, is still unknown

Natural Bridge

Torndirrup National Park on Western Australia’s southern coast faces the ocean, along the coast where Australia and Antarctica split apart during the final breakup of Gondwanaland about 50 million years ago. Prior to that breakup, the two continental landmasses rode along the Earth’s surface together for over a billion years, following a continental collision.

TREASURES OF THE ANCIENT WORLD: The Rosetta Stone (Egypt)

THE Rosetta Stone is an incomplete grey and pink granodiorite stela dating from 196 BCE, which portrays a priestly decree about King Ptolemy V of Egypt. The text on the stone is written in three different variations: Hieroglyphic, Greek and Demotic.

The stone was discovered at Port Saint Julien, el-Rashid (Rosetta) on the Nile Delta in Egypt in 1799 by Pierre Francois Xavier Bouchard, (an officer of engineers in Napoleon’s army).
