How Old Is the Mount St. Helens Lava Dome?

All rights reserved. Update: Our new Yellowstone National Park stories may surprise you with pictures of Yellowstone’s remarkable animals. On August 29, , a year-old Army lieutenant named Gustavus Doane, part of an exploratory expedition in the Yellowstone region in the territory of Wyoming, scrambled his way to the summit of Mount Washburn above the Yellowstone River. Looking to the south, he noticed that something was missing from a stretch of the Rocky Mountains: mountains.

For miles and miles, the only elevations were in the distance, forming parentheses around a huge forested basin.

To bad Penn State can’t take back their degree. Post a Comment. The problem YECers face, the rest of the world had moved far and beyond our understanding of the age of the Earth once dictated by Ussher. And thanks to the discovery of radioactive decay during the turn of the twentieth century, it is now well established that the age of the planet is 4. The science of geochronology is well established and had been for at least the past sixty years.

This is a science that is able to measure the radioactive decay rates of certain elements trapped in certain crystals zircons that formed inside mostly igneous rocks to obtain an absolute age. The concept is relatively simple. Determine the ratio between parent isotopes to daughter isotopes, which the half-life of the isotopes is known to obtain an absolute age of the sample being tested. There are some limitations to geochronology like most techniques will not provide accurate results for recently formed samples and errors will sometime occur because the sample was not properly processed, nor can one obtain accurate results from samples obtained from sedimentary rocks or metamorphic rocks.

Tens of thousands of samples are worked on each year, with highly accurate results, despite YECers attempts to pull out the odd Irish pennants. Geochronology is a form of positive evidence that the earth is old. But, YECers insist is very young. ICR will allow for a time frame of 6, to 10, years old, however AiG accepts only the chronology established by the seventeenth century Irish Anglican cleric.

Despite several half-hearted attempts like focusing on magnetism and amount of salt in the seas, YECers have no positive evidence to support their position, none whatsoever.

Showing Their Age

Mount Sidley is a complex, polygenetic stratovolcano composed primarily of phonolitic and trachytic lavas and subordinate pyroclastic lithologies at the southern extremity of the Executive Committee Range, a linear chain of volcanoes in central Marie Byrd Land, Antarctica. This was followed 4. The final phase of activity was the eruption of basanite cones at approximately 4. The southward migration of volcanic activity was accompanied by distinct changes in magma composition and is best explained by the sequential release of magmas stored within an intricate system of conduits and chambers in the crust by tectonically driven magma assisted?

The radioactive dating controversy of a fossil known as Skull KNM-ER is well-documented. The radioisotope methods used for rocks, potassium-argon (​K-Ar), Lava from the Mt. Rangitoto eruption which happened years ago has Lava from a Mount St. Helens lava dome has just been dated at +/-

The belief that radiodating methods give absolute measurements of time is widespread as a result of scientific popularization in journals, conferences, and the media. In fact, due to the difficulties in applying the experimental method to events in the past, all chronometers based on natural or artificial nuclear disintegration need a calibration. This calibration supposes a great number of basic assumptions concerning initial conditions.

The choice of these initial conditions affects the results. These assumptions are not demonstrated, only supposed to be true. The discussion of some phenomena taking place during rock crystallization reveals huge discrepancies between the model theory and the reality. This excess argon greatly alters the calculated age and puts into question the validity of the method. These investigations suppose complete coordination between different disciplines and laboratories.

The experimental method can solve scientific questions and problems by using instruments, measurement procedures, and data treatment. The results, taking into account previous knowledge and discussion with other specialists, help to give an interpretation or build a theory. Experiments and measurements need to be accurate, explainable and reproducible. Figure 1 shows the complex intellectual process using previous knowledge and experiments to arrive at a conclusion or hypothesis.

The most important point of the procedure consists in the discussion and confrontation with other possible explanations. Applied to presently observable phenomena, it is always possible for other scientists to reproduce the experiments.

Mount Mazama and Archaeological Dating

However, it did not start this way. It was once the top of Mount Mazama, a supervolcano in the Cascade Range that towered over 12, feet above sea level. The transition from enormous mountain to the caldera it is today was explosive: about 7, years ago Mount Mazama erupted, emptying twelve cubic miles of lava and enormous amounts of pumice out of its magma chamber in mere days, during an eruption forty times as powerful as the eruption of Mount St. The magma chamber then collapsed in on itself, forming the caldera, which filled to form Crater Lake.

During this explosion, Mount Mazama also erupted an enormous ash plume.

Archaeological finds worldwide have helped researchers to fill out the story of human evolution and migration. An essential piece of information in this research is the age of the fossils and artifacts. How do scientists determine their ages? Here are more details on a few of the methods used to date objects discussed in “The Great Human Migration” Smithsonian , July :. In a cave in Oregon, archaeologists found bones, plant remains and coprolites—fossilized feces.

DNA remaining in the coprolites indicated their human origin but not their age. For that, the scientists looked to the carbon contained within the ancient dung. By definition, every atom of a given element has a specific number of protons in its nucleus. The element carbon has six protons, for example. But the number of neutrons in the nucleus can vary.
