ARIZONA : the American Southwest - Saguaro

grand canyon state

Giant Saguaro Cactus, Sabino Canyon, Tucson, Arizona


From Wikipedia, the free encyclopedia

The saguaro (/səˈwɑroʊ/) (Carnegiea gigantea) is an arborescent (tree-like) cactus species in the monotypic genus Carnegiea, which can grow to be over 20 m (70 ft) tall. It is native to the Sonoran Desert in Arizona, the Mexican State of Sonora, and the Whipple Mountains and Imperial County areas of California. The saguaro blossom is the state wildflower of Arizona. Its scientific name is given in honor of Andrew Carnegie.

Some saguaros are "crested" due to fasciation.
Saguaros have a relatively long lifespan. They may grow their first side arm any time from 75–100 years of age, but some never grow one at all. A saguaro without arms is called a spear.

The arms are grown to increase the plant's reproductive capacity (more apices lead to more flowers and fruit). The growth rate of saguaros is strongly dependent on precipitation; saguaros in drier western Arizona grow only half as fast as those in and around Tucson, Arizona. Some specimens may live for more than 150 years;[3] the largest known saguaro is the Champion Saguaro growing in Maricopa County, Arizona, and is 13.8 m (45.3 ft) tall with a girth of 3.1 m (10 ft). These cacti can grow from 40 to 60 ft tall. They grow slowly from seed, and never from cuttings. Whenever it rains, saguaros soak up the rainwater. The cactus will visibly expand, holding in the water. It conserves the water and slowly consumes it.

The spines on saguaro having a height less than 2 m grow rapidly, up to a millimeter per day. When held up to the light or bisected, alternating light and dark bands transverse to the long axis of spines can be seen. These transverse bands have been correlated to daily growth. In columnar cacti, spines almost always grow in areoles which originate at the apex of the plant. Individual spine growth reaches mature size in the first season and then ceases to grow. Areoles are moved to the side and the apex continues to grow upwards. Thus, the older spines are towards the base of a columnar cactus and newer spines are near the apex. Current studies are underway to examine the relationship of carbon and oxygen isotope ratios in the tissues of spines to the past climate and photosynthetic history of the plant (acanthochronology).

The night-blooming white and yellow flowers appear April through June and the sweet, ruby-colored fruit mature by late June. Saguaro flowers are self-incompatible, thus require crosspollination. Large quantities of pollen are required for complete pollination as there are numerous ovules. A well-pollinated fruit will contain several thousand tiny seeds.

The flowers open well after sunset and remain open till mid-afternoon of the next day. They also continue to produce nectar after sunrise. Saguaros have a redundant pollination system, i.e. full fruit set is possible even if only a fraction of the pollinating species are present. Main pollinators are honey bees, bats and white-winged doves. In most years diurnal visitors are the main contributors for fruit set, with the highest proportion on honey bees.

Main nocturnal pollinator is the Lesser Long-nosed Bat, feeding on the nectar. A number of floral characteristics are geared toward bat pollination: nocturnal opening of the flowers, nocturnal maturation of pollen, very rich nectar, position high above the ground, durable blooms that can withstand a bat's weight, and fragrance emitted at night. One additional piece of evidence is that the amino acids in the pollen appear to help sustain lactation in bats.

Other diurnal visitors are birds like the Costa's hummingbird, Black-chinned hummingbird and Broad-billed hummingbird, the Hooded oriole and Scott's oriole, the Gila woodpecker and Gilded flicker, the Verdin and the House finch.

The ruby red fruits are 6–9 cm long and ripen in June. Each fruit contains around 2000 seeds plus sweet fleshy connective tissue. The fruits are edible and prized by local people.

The fruits cannot be picked by hand, but must be harvested using a pole (often a saguaro rib) 2 to 5 m long, to the end of which is attached another pole.

The O'odham tribes have a long history of saguaro fruit use. The Tohono O’odham tribes celebrate the beginning of their summer growing season with a ceremony using a fermented drink made from the bright red fruit to summon rains, vital for the crops.

Native birds such as Gila woodpeckers, purple martins, house finches, and gilded flickers live inside holes in saguaros. Flickers excavate larger holes higher on the stem. The nest cavity is deep, the parents and young entirely hidden from view. The saguaro creates callus tissue on the wound. When the saguaro dies and its soft flesh rots, the callus remains behind as a so-called "saguaro boot", which was used by natives for storage.

The Gila woodpeckers (Melanerpes uropygialis) create new nest holes each season rather than reuse the old ones, leaving convenient nest holes for other animals, such as elf owls, flycatchers, and wrens. In recent years, early-breeding, aggressive, non-native birds have taken over the nests to the detriment of elf owls that breed and nest later.

Harming a saguaro in any manner, including cactus plugging, is illegal by state law in Arizona, and when houses or highways are built, special permits must be obtained to move or destroy any saguaro affected. There are exceptions to this general understanding. For example, a private landowner whose property is ten (10) acres or less, where the initial construction has already occurred, may remove a saguaro from the property. This is common when the cactus falls over in a storm, its location interferes with a house addition, or it becomes a potential hazard to humans. Specifically, Arizona Revised Statutes, A.R.S. 3-904.(H) defines this exemption.

The saguaro is an important source of food and shelter for the Tohono O’odham. Saguaro spines are sometimes used as sewing needles and the ribs are used to make harvesting tools.

The ribs of the saguaro were used for construction and other purposes by Native Americans. A fine example can be seen in the roofing of the cloisters of the Mission San Xavier del Bac on the 

Tohono O'odham lands near Tucson.

The Seri people of northwestern Mexico used the plant, which they call mojépe, for a number of purposes.

The saguaro is often used as an emblem in commercials and logos that attempt to convey a sense of the Southwest, even if the product has no connection to Arizona or the Sonoran Desert. For instance, no naturally occurring saguaros are found within 250 miles (400 km) of El Paso, Texas, but the silhouette is found on the label of Old El Paso brand products. Though the geographic anomaly has lessened in recent years, Western films once enthusiastically placed saguaros in Monument Valley of Arizona, as well as New Mexico, Utah, and Texas. There are no wild saguaros anywhere in Texas, Colorado, Utah, or Nevada, nor in the high deserts of northern Arizona.

The Canyon A R I Z O N A grand canyon state

Sundown near Bitter Springs, Arizona

Marble Canyon is the section of the Colorado River canyon in northern Arizona from Lee's Ferry to the confluence with the Little Colorado River, which marks the beginning of the Grand Canyon.

Lee's Ferry is a common launching point for river runners starting their journey through the Grand Canyon. Marble Canyon is also well known for the Navajo Bridge, where US Highway 89A crosses the Colorado River.

Marble Canyon marks the western boundary of the Navajo Nation. In 1975, the former Marble Canyon National Monument, which followed the Colorado River northeast from the Grand Canyon to Lee's Ferry, was made part of Grand Canyon National Park.

The name Marble Canyon is a misnomer because there is no marble there. Although Powell knew this when he named the canyon, he thought the polished limestone looked like marble. In his words, "The limestone of the canyon is often polished, and makes a beautiful marble. Sometimes the rocks are of many colors - white, gray, pink, and purple, with saffron tints"

Marble Canyon is the site of one of the last great proposed dam projects on the Colorado, the Marble Canyon Dam. Proposed and investigated in the early 1950s by the United States Bureau of Reclamation, the proposal met substantial opposition, notably from the Sierra Club, when a revived proposal was considered by the state of Arizona as part of the Central Arizona Project from 1965 to 1968. The proposed dam was finally abandoned in 1968. Exploratory holes, which were drilled in the Redwall Limestone of the canyon walls in an early phase of the abortive project, can still be seen at Mile 39.2.

TOKYO : Daigo Fukuryu Maru - Tokyo Metropolitan Gov't


 Daigo Fukuryu Maru Exhibition Hall, Koto-ku, Tokyo

Daigo Fukuryu Maru

Daigo Fukuryū Maru (第五福龍丸, S.S. Lucky Dragon 5) was a Japanese tuna fishing boat, with a crew of 23 men, which was exposed to and contaminated by nuclear fallout from the United States' Castle Bravo thermonuclear device test on Bikini Atoll, on March 1, 1954.

Aikichi Kuboyama, the boat's chief radioman, died less than seven months later of liver cirrhosis on September 23, 1954, having suffered along with the 22 other crew members of acute radiation syndrome (ARS) for a number of weeks after the Bravo test in March. Due to ARS treatment, the crew began to recover, Kuboyama's cause of death in late September is regarded to have been due to underlying liver cirrhosis compounded by an infection.  The majority of medical experts believe that the crew members were infected with hepatitis C through blood transfusions during part of their ARS treatment. Kuboyama is considered the first victim of the hydrogen bomb of test shot Castle Bravo.

Lake Toya

Lake Tōya (洞爺湖 Tōya-ko) is a volcanic caldera lake in Shikotsu-Toya National Park, Abuta District, Hokkaidō, Japan. It is a part of "Toya Caldera and Usu Volcano Global Geopark" which joins in Global Geoparks Network. The stratovolcano of Mount Usu lies on the southern rim of the caldera. The lake is nearly circular, being 10 kilometers in diameter from east-west and 9 kilometers from North-South. The lake's biggest town, Tōyako is located on its western shore. The town Sōbetsu is located on the other side of the lake.

Lake Tōya is said to be the northernmost lake in Japan that never ices, and the second most transparent lake in Japan. Nakano-shima, an island in the middle of the lake, houses the Tōya Lake Forest Museum.

Lake Tōya was called Kim'un-to (キムウン (kim'un) means "in the mountain" and ト (to) means "lake") by the Ainu. In the Meiji era, Japanese pioneers named the lake Tōya after the Ainu expression to ya, which means "lakeland."

The 2008 G8 Summit was held at Lake Tōya and The Windsor Hotel Toya Resort & Spa.
