How Archaeologists Uncover History With Trees

The enhanced detail of plate tectonic processes provided by these new data did not, however, result in such a dramatic advance as would have been expected. Hot spots and mantle plumes were by then firmly established concepts in explaining the observed linear chains of volcanic islands and in providing a super-deep mantle frame of reference the hotspot reference frame that was independent of plate motions at the surface. Accumulating scientific evidence over half a decade and recent GPS-derived absolute plate motions suggest that both the mantle plume frame of reference and the age dependence along volcanic lineaments are not as strong as once believed. This article investigates the complex tectono-magmatic processes involved in the opening of the Central, Equatorial and South Atlantic Ocean and asks the simple question of whether there is an alternative tectonic model to explain the phenomena seen in the satellite gravity field. The case is made that hot spots or mantle plumes are not necessarily required to explain the volcanic lineaments and that most, if not all, features result from deformational processes during the evolution of the plates. Such a model has a range of implications which, hopefully, can be tested to further refine the model. To evaluate and develop the proposed model the resolution of the satellite gravity needs to be increased to about 10 km. The need for such resolution is illustrated in this study and will significantly improve our understanding of oceanic crust-forming processes, particularly the role of magmatism and intra-plate deformation, 2.

Rio Grande Blankets: Late Nineteenth-Century Textiles in Transition [Kellen Kee McIntyre] on *FREE* shipping on qualifying offers. New Copy. From the Foreword: The twenty-seven blankets reproduced and analyzed in this book were woven by Hispanic weavers in New Mexico from the mid-nineteenth century to about ¹ Because many of these weavers lived in the Rio Grande Valley.

Colcha embroidery is a traditional Spanish colonial style of textile, bed covering, or wall hanging dating from the early nineteenth century. In the first book to consider this craft, Suzanne MacAulay provides a detailed account of this folk art tradition that is both old and constantly renewing itself, presenting a sensitive portrayal of artists and the contexts in which they live and work.

Stitching Rites reveals how art, history, and memory interweave in a rich creative web. Based on archival research and on extensive interviews with artists, the book reveals the personal motivations of the embroiderers and their relationships with their work, with each other, with their community, and with outsiders. Through stitchers like Josephine Lobato and the San Luis Ladies Sewing Circle, MacAulay shows how colcha creation is bound up in a perpetual round of cultural commentary and self-reflection.

MacAulay includes detailed descriptions of changes in stitching techniques, themes, and styles to show the impact of a wide range of outside influences on the lives of the artists and on the art form.

The Rio Grande rift is a north-south trending zone of approximately east-west oriented extension that bisects the state of New Mexico. The extension is due to the Colorado Plateau pulling away from the High Plains, which causes the Earth’s crust to be stretched and thinned.

This process created a gap that was 40 mile wide, several miles deep, and flanked by fault block uplift mountain ranges to the east and volcanic features to the west. Over time a unique ecosystem with rich biodiversity derived from a variety of adjacent bioregions has evolved. Threatened Habitat Throughout most of its history, the Rio Grande Bosque has been a system of wetlands, oxbow lakes, sandbars, and woodlands that migrated with the wild and changing meander of the river.

Seasonal flooding cleared debris and enriched the soil. Cottonwoods along with Gooding and Coyote Willows germinated and thrived in the periodic floods and high water table. With the growing numbers of Anglo migrants in the valley came large-scale agriculture, irrigation systems, livestock grazing, and logging. These activities in turn created soil erosion, a large sediment load in the river, and increased flooding. To control flooding, a series of major interventions ensued.

The 20th century was marked by the construction of major dams including Elephant Butte in , Jemez Canyon in , Abiquiu in , Galisteo in , and Cochiti in along with hundreds of miles of irrigation canals. Additional engineering projects included the draining of wetlands, dredging and entrenching of the river, and the installation of jetty jacks.

It includes properties in the eastern half of adjacent Wimpy, Second, Main, and Mirasoles streets, and their intersecting side streets, an area which comprised the main part of the downtown shopping district throughout the late 19th and early 20th centuries. Rio Grande City has a long and colorful history dating from its 18th century origins as a Spanish land grant to its place in the Mexican and American Civil Wars and as a Calvary post through the first half of the 20th century.

Land grants on the lower Rio Grande Valley were long, narrow ribbons known as porciones. Porciones spanned the river cross-wise to give each property owner at least a modicum of river frontage. Although their property lay on both sides of the Rio Grande River, nearly all the landowners lived on the south side of the river, in present Mexico, and conducted only modest ranching operations on the north.

One of the principle reasons was that there were more established communities or villas with greater numbers of people to guard against American-Indian attacks on the south side of the river. American-Indian attacks on isolated ranching outposts on the north side of the river were relentless throughout the 18th and well into the 19th centuries.

Originally published in Ancient American magazine. It was a war owning many battles, and had an incredible loss of life. It probably spanned the geography of a number of present day states—commencing from the area that is the boundary line of the ancient Mississippi. Our archaeological record holds relatively limited data of this time period, much less this proposed event, and thus we are dependent to some extent on the invaluable resource of Native American transmission.

However, many pieces to the puzzle are now thought to be in place. The Archaic populace is not believed to have constructed mounds in the Ohio Valley region, although this is not known for certain due to several factors, including widespread destruction of the earthworks, without content cataloging, over the last years.

Most understanding is based upon the dating and trait-grouping of materials found in the diminished number of mounds and village sites yet existing after a formal discipline in archaeology and anthropology finally took over excavation and detailed record keeping. There are Archaic era mounded structures, often intricate and complex, in the deep southern U.

For this reason, theories have been put forth that the moundbuilding tradition came into the Ohio Valley around the time of the Adena from the southern Mississippi, thereby tentatively associating the Adena people with older cultures from the south. In one way of looking at this idea, it supposes that moundbuilding was a phenomenon peculiar to only one geographical source, necessarily having been passed on.

Generally the Adena had more massive bone structure, according to these same studies. The pre-eminent theory of Adena origin at the time was that their ancestry had come from Mexico or even further south. However, the Adena body bone structure type was unusually difficult to trace with surety south of the Rio Grande—where another distinguishing Adena-resonant trait was found practiced from earlier times.

Shaping was an addition to this already distinguished skull type.

Construction began on this church in , considered today as the best surviving example of Spanish Baroque architecture in the U. Local building materials, especially adobe, and simplified Baroque-style features for churches and missions. In the American Southwest the Spanish colonists relied on single-story adobe structures with generally flat roofs and parapets, not much different from the Pueblo Indian tribes of the Rio Grande Valley. Mission churches were typically more elaborate with Baroque elements, but simpler and smaller the further one moved northward from Mexico.

Many towns and cities in the South and West still clearly reveal the street grid, central plaza, and local Spanish church of the original settlements. Spanish settlements and related architecture can be classified as three distinct types, or functions: Spanish mission churches — and simpler local community churches — generally included features derived from the Baroque period in Europe, particularly of the Spanish variety during the 17th and 18th centuries.

Baroque features could include rather elaborate facades with round arches, domes, and niches for statuary; prominent belfries or bell towers, curved parapets extending above the entryway, and typically symmetrical facades if twin bell towers. Residential buildings, sometimes called placitas courtyard houses , might be added to over a period of decades, with the intention of fully enclosing an interior courtyard.

Such courtyard houses were popular in the Mediterranean region at the time, the style dating back to the time of Christ. Many of them in the colonies never attained that growth, however, and so remain rectangular or L-shaped to this day. In whatever configuration, they were typically one story tall with flat roof and adobe construction. Vigas protruding wooden beams are usually visible extending out from the roofline, and any portales porches would be supported with thick wooden columns and zapata capitals carved, wooden capitals atop the columns.
