Are they somthing else? Thanks Discount Fiestaware – 26th Nov, 09 There is old and new Fiesta that have no stamp at all, such as the gusto bowls. It can be tough to date Fiesta with no markings — it all ces down to identifying the color and determining if that particular piece was produced by HLC. Tell us more about your Fiesta Karlie – 27th Nov, 09 That was very informative, and know i am looking in my cupboards to see how old my new fiesta is Jane Schenck – 2nd Jan, 10 The newer ones have the ink stamp. But one piece, a covered butter dish only has a rather crude Fiesta molded into the bottom, the E in fiesta looks like uppercase, but only the E, and in another area at the side of the bottom of the dish is a small white C. It is in a rose color. I read somewhere about fake butter dishes.

The forest in which these trees now stands is part of the traditional territories of the Algonquin First Nations. First Nations peoples settled this area and traversed what is now the Silverthorn Forest, relying on both the rich bounty of deciduous and coniferous trees and clear waters of Etobicoke Creek. Silverthorn Forest is the last remaining stand of the Carolinian Forest in this area, a forest that once spanned from southern Ontario down to the Carolinas.

This remnant of the original stand remains today thanks to the foresight of the original farming family, the Silverthorns and the subsequent developer, Mark Cavotti, both of whom wanted the forest to remain intact for future generations. This Heritage Tree has been in the Gleeson Family since , growing on their farmland. Steve Gleeson, the current landowner, reports that his grandfather Gerald Gleeson, born recalled the tree as a small seedling.

In fact, it seems one secret to their longevity is the harsh environment in which most bristlecone pines grow. Bristlecone pines in Great Basin National Park grow in isolated groves just below treeline. Conditions are harsh, with cold temperatures, a short growing season, and high winds. Bristlecone pines in these high-elevation environments grow very slowly, and in some years don’t even add a ring of growth.

This slow growth makes their wood very dense and resistant to insects, fungi, rot, and erosion. Vegetation is very sparse, limiting the role of fire. Bristlecone pine seeds are occassionally cached by birds at lower elevations. Bristlecone pines grow more rapidly in more “favorable” environments at lower elevations.

A pH of 7 is neutral, acidic soils have a pH of less than 7 and alkaline soils have a pH of greater than 7. Phloem- also known as inner bark, phloem transports dissolved nutrients from the leaves to the other parts of trees and woody plants Photogrammetry – the science of interpreting and making reliable measurements from aerial photographs Photosynthesis – the process by which plants manufacture simple sugars in the presence of sunlight, carbon dioxide and water.

Chlorophyll is essential to the process Plantation – an artificially reforested area established by planting or direct seeding and usually made up of a single species Point Source Pollution – sources of water pollution generally a man-caused pollutant which can be traced to a specific place or location i. The sun, wind, falling water and trees are examples of renewable resources Residual Stand – trees, often of saw log size, left in a stand after logging to grow until the next harvest Residual Trees – live trees left standing after the completion of harvesting Rill Erosion – an erosion process in which numerous small channels only several inches deep are formed; occurs mainly on disturbed and exposed soils Riparian – vegetation that grows close to water; creeks, springs, small lakes or swamps.

Carbon 14 is used for this example: This nullifies the carbon method as well as demonstrating that the earth is less than 10, years old. The above is offered as a simple fact of research. Knowing how faulty creationist “facts” can be, let’s do a little research of our own. One suspects that the scientific world would not be using the carbon method if it were so obviously flawed.

Could it be that the whole scientific community has missed this point, or is it another case of creationist daydreaming? This argument was popularized by Henry Morris , p. In another creationist, Robert L. Whitelaw, using a greater ratio of carbon production to decay, concluded that only years passed since carbon started forming in the atmosphere!

In this particular exercise, we wish to examine whether there is a relationship between local climate precipitation and tree rings using white oak Quercus alba in southeastern Ohio. Each field team should obtain the appropriate field supplies from their instructor and obtain 3 increment cores from white oak trees at the chosen field site.

Please consult Field Methods for a detailed description of the field equipment, including its use and care, and the actual methods of core collection and preservation. Return your increment cores to the laboratory. The cores should next be mounted and glued in to increment core holders and then the surface prepared for study following the protocols outlined in Lab Methods. Following surface preparation, you can begin the process of crossdating.

How Good Are Those Young-Earth Arguments?

The following article is primarily based on a discussion of radiocarbon dating found in The Biblical Chronologist Volume 5, Number 1. Full details and references can be found there. Radiocarbon dating is based on a few relatively simple principles. There are many carbon atoms in our environment.

Mahapadma Nanda became King of Magadha and created what looks like the first “Empire” in Northern India. While Indian history begins with some confidence with the Mauyras, the Nandas are now emerging into the light of history with a little more distinctness.

Alternating patterns of distinct laminae are commonly identified within glacial lake deposits and are generally interpreted in the following way: However, there is actually no empirical evidence to back the claim that varves form as annual deposits over extended periods of time. It appears then, that claiming a varve is an annual event is an assumption in itself; one steeped in uniformitarian thought, but not reality.

Geologists have known for quite some time that multiple laminae may form very rapidly. French creation scientist Guy Berthault performed groundbreaking laboratory experiments demonstrating that multiple laminations can form spontaneously when sediment mixtures consisting of particles of different sizes are deposited in air, running water, or still water.

This occurs because particles of different sizes have a tendency to spontaneously segregate and stratify themselves.

The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years. We are told that these methods are accurate to a few percent, and that there are many different methods.

We are told that of all the radiometric dates that are measured, only a few percent are anomalous. This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points.

Lakes, meadows, and wooded paths stretching over a good portion of Golden Gate Park’s length, the middle section has some of the most tranquil and secluded areas in the park. Most of the lakes in the park, including the lush Stow Lake, did not exist at all before the creation of the park.

Do Varves, Tree-Rings, and Radiocarbon Measurements Prove an Old Earth?

Atmospheric nuclear weapon tests almost doubled the concentration of 14C in the Northern Hemisphere. One side-effect of the change in atmospheric carbon is that this has enabled some options e. The gas mixes rapidly and becomes evenly distributed throughout the atmosphere the mixing timescale in the order of weeks. Carbon dioxide also dissolves in water and thus permeates the oceans , but at a slower rate.

The transfer between the ocean shallow layer and the large reservoir of bicarbonates in the ocean depths occurs at a limited rate. Suess effect Many man-made chemicals are derived from fossil fuels such as petroleum or coal in which 14C is greatly depleted.

The fact that even high-technological methods, such as neutron imaging and SXFM analyses, do not aid the identification of true tree-ring borders from IADFs demonstrates that the problematic dating is not a detection problem and instead related to the intrinsical biological nature of olive tree-rings.

This species and others such as Dryopithecus existed before the hominid line diverged on the path to humans. This lineage ancestral gibbons is believed to have diverged from the great ape and human lineages between 17 and 25 Mya Avers, Oreopithecus ‘s hand closely matches the pattern of early hominids, with a grasping capability including firm pad-to-pad precision gripping that apes are unable to perform presumably as a response to similar functional demands to hominids Moya-Sola et al, Bipedal activities made up a significant part of the positional behavior of this primate Kohler and Moya-Sola, Gorilla and human DNA only differs by 2.

Research illuminates inaccuracies in radiocarbon dating June 5, by Daniel Aloi, Cornell University Sturt Manning cores a multi-century old Juniperus phoenicea tree near Petra in southern Jordan. Cornell University Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material. But new research shows that commonly accepted radiocarbon dating standards can miss the mark—calling into question historical timelines.

Archaeologist Sturt Manning and colleagues have revealed variations in the radiocarbon cycle at certain periods of time, affecting frequently cited standards used in archaeological and historical research relevant to the southern Levant region, which includes Israel, southern Jordan and Egypt. These variations, or offsets, of up to 20 years in the calibration of precise radiocarbon dating could be related to climatic conditions.

Dendrochronology is based on the phenomenon that trees usually grow by the addition of rings. Dendrochronological findings played an important role in the early days of radiocarbon dating. Tree rings provided truly known-age material needed to check the accuracy of the carbon dating method.

Probably India did not have a clear local name earlier because, like China , it seemed to be the principal portion of the entire world, and so simply the world itself. Sumeru or Meru , the only one inhabited with humans identical to us. The only question was how much of it was taken up by India. Indeed, India was once an island in the Mesozoic Ocean, but it moved north and collided with Asia.

In Chinese, we get various ways of referring to India. The modern form, , renders the name phonetically with characters of no particular semantic significance “print, stamp, or seal” and “a rule, law, measure, degree”. The older practice, however, was dedicated characters that might have a larger meaning. Thus, we get or , in which can be a kind of bamboo but otherwise is just used for India.
