In the past two months or so the dome-shaped formation of rock in the crater has been developing a large bulge, and frequent plumes of gas have been seen rising from the crater. These are clear signs of volcanic activity and they are very similar to what was seen before the eruptions of Latest reports tell of a steam plume rising passively and drifting south and south-westward over the crater rim. The plume occasionally contains minor ash, which falls in the crater and on the southern flank of the volcano, darkening the new snow. Seismic activity remains low compared to that observed earlier, and is consistent with a slow but continuous rise of magma driving up the crater floor and feeding a surface extrusion of lava. The overall low rates of seismicity and gas emission suggest that the lava reaching the surface does not contain much gas. This is good news, since it means that highly explosive eruptions are less likely in the near future.

Dating the rocks of Mt. St. Helens
June 15, ] I failed to realize how much the facts concerning the volcanic eruption at Mt. Helens have been abused and misused by creationists until I read the series of articles on June 15, at http: This web page contains many of the misinterpretations, misrepresentations, and factual distortions that creationists have concocted surrounding the eruption at Mt. The most striking aspect of these web pages is the total lack of any citations or references for the claims being made.
Mt. St. Helens erupted in , sending out gas and pyroclastics. Geologists have found evidence of many eruptions of St. Helens, dating back 37, years. The mountain is huge and is composed of layers of lava and pyroclastics.
Helens was a series of small earthquakes that began on March 16 After hundreds of additional earthquakes, a steam explosion on March 27 blasted a crater through the volcano’s ice capped summit. Within a week the crater had grown to about 1, feet in diameter and two giant crack systems crossed the entire summit area. By May 17, more than 10, earthquakes had shaken the volcano and the north flank had grown outward at least feet to form a noticeable bulge.
Such dramatic deformation of the volcano was strong evidence that molten rock magma had risen high into the volcano. The landslide depressurized the volcano’s magma system, triggering powerful explosions that ripped through the sliding debris. Rocks, ash, volcanic gas, and steam were blasted upward and outward to the north.
This lateral blast of hot material accelerated to at least miles per hour, then slowed as the rocks and ash fell to the ground and spread away from the volcano; several people escaping the blast on its western edge were able to keep ahead of the advancing cloud by driving 65 to miles an hour! The blast cloud traveled as far as 17 miles northward from the volcano and the landslide traveled about 14 miles west, down the North Fork Toutle River.
Less than an hour later, a second eruption column formed as magma erupted explosively from the new crater. Then, beginning just after noon, swift avalanches of hot ash, pumice, and gas pyroclastic flows poured out of the crater at 50 to 80 miles per hour and spread as far as 5 miles to the north.
Mount St. Helens
Helens, located in southwestern Washington about 50 miles northeast of Portland, Oregon, is one of several lofty volcanic peaks that dominate the Cascade Range of the Pacific Northwest; the range extends from Mount Garibaldi in British Columbia, Canada, to Lassen Peak in northern California. Geologists call Mount St. Helens a composite volcano or stratovolcano , a term for steepsided, often symmetrical cones constructed of alternating layers of lava flows, ash, and other volcanic debris.
Composite volcanoes tend to erupt explosively and pose considerable danger to nearby life and property. In contrast, the gently sloping shield volcanoes, such as those in Hawaii, typically erupt nonexplosively, producing fluid lavas that can flow great distances from the active vents. Although Hawaiian-type eruptions may destroy property, they rarely cause death or injury.
What Austin did was to exploit a known caveat in radiometric dating; dramatically illustrate it with a high-profile test using the public’s favorite volcano, Mount St. Helens; and sensationalize the results in a paper that introduces nothing new to geologists, but that .
The fact that the readership largely consists of unsuspecting laypeople makes this all the more inexcusable. All dating methods related to the unobservable past rely on unverifiable assumptions, chief of which is the one about closed systems. Furthermore, all dating methods involve the subjective evaluation of data and results, so much so, that their veracity must seriously be questioned.
Recent attempts to extend the radiocarbon 14C dating method back in time provide an instructive example of how age determinations are manipulated. National Geographic magazine NG , an American periodical, is well known worldwide for its beautiful photographs and outstanding depictions of nations and cultures. Unfortunately, and especially so in recent years, National Geographic magazine has increasingly deviated from the subject of geography and become a virtual propaganda mouthpiece for evolutionary speculations.
Now even evolutionists have abandoned this creature, now called Paranthropus, as a missing link, but the effect was profound at the time. Later, as an adult and ex-evolutionist, Dr. A recent NG article [ 2 ] has presented the unsuspecting reader with a totally one-sided and uncritical portrayal of the dating methods used by conventional uniformitarian geologists. Evidently, NG is now being pressed into service as a cheerleader for the dogmas of the old Earth and Universe.
To rectify this situation, I briefly outline here some of the many fallacies of isotopic dating [ 3 ] and discuss some recent developments in the field of age determination. The NG article lumps all dating methods together, regardless of their assumptions or the span of time supposedly measured by the dating method.
Implicitly, it seems there is a deceptive equating of different dating methods.
Problems from Unexplained Anomalies
Danau Toba is a lake and supervolcano, kilometres long and 30 kilometres wide, and metres 1, ft at its deepest point. It is the largest volcanic lake in the world. In addition, it is the site of a supervolcanic eruption that occurred about 74, years ago, a massive climate-changing event. The eruption is believed to have had a VEI intensity of 8.
This eruption is believed to have been the largest anywhere on Earth in the last 25 million years.
Because of the Mount St. Helens eruption, scientists know that sedimentary rock layers can form in only hours, rather than requiring millions of years. It also showed that radiometric dating is not necessarily accurate and that God gave animals and plants the ability to rapidly re-colonize barren land.
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. Since there doesn’t seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as accurate.
However, this causes a problem for those who believe based on the Bible that life has only existed on the earth for a few thousand years, since fossils are found in rocks that are dated to be over million years old by radiometric methods, and some fossils are found in rocks that are dated to be billions of years old. If these dates are correct, this calls the Biblical account of a recent creation of life into question. After study and discussion of this question, I now believe that the claimed accuracy of radiometric dating methods is a result of a great misunderstanding of the data, and that the various methods hardly ever agree with each other, and often do not agree with the assumed ages of the rocks in which they are found.
I believe that there is a great need for this information to be made known, so I am making this article available in the hopes that it will enlighten others who are considering these questions.
Remember Mount St. Helens and heed the lessons learned
Ecological Succession in Mount St Helens by Jessica Liang The word eruption cultivates mental images of catastrophic events, and perhaps more close to heart, and eruption of Mount St. But despite the enormous destruction and loss wreaked by this eruption, it also set forth an equal potential for creation. The eruption created a unique opportunity for scientists and researchers to study the changes the natural destruction wrought on the landscape.
This paper also discusses Mount St. Helens K-Ar dating, and historic lava flows and their excess argon. So magma holds tremendous amounts of argon. Now, .
Helens It was awesome to see Randy and Kristen rolling into the campground on Friday. These two were our inspiration to get on the road. In , Randy agreed to work in New York on a machine installation for a year. He and Kristen packed everything up and lived in a RV for that year. After that they moved to Nevada and lived in their RV until buying a house two years ago.
We went to visit them in New York and loved what they were doing. No house to maintain, new places to see and living simply. It took us a while, but we finally got there! We are enjoying the same freedom they felt when they took off all those years ago. We were so happy when they wanted to meet us anywhere for a visit. Our spots at Timberlake Campground We settled in at adjoining campsites and it felt like old times.
Carbon Dating Undercuts Evolution
Young-Earth Creationist ‘Dating‘ of a Mt. St. Helens Dacite: The Failure of Austin and Swenson to Recognize Obviously Ancient Minerals Kevin R. Henke, Ph.D. The following material may be freely copied and distributed as long as the author is properly acknowledged.
The conventional K-Ar dating method was applied to the dacite flow from the new lava dome at Mount St. The whole-rock age was 0. Ages for component minerals varied from 0. These ages show that the K-Ar method is invalid. Creation Ex Nihilo Technical Journal 10 3: Austin sent his samples to a laboratory that clearly states that their equipment cannot accurately measure samples less than two million years old.
All of the measured ages but one fall well under the stated limit of accuracy, so the method applied to them is obviously inapplicable. Since Austin misused the measurement technique, he should expect inaccurate results, but the fault is his, not the technique’s. Experimental error is a possible explanation for the older date. Austin’s samples were not homogeneous, as he himself admitted.
Any xenocrysts in the samples would make the samples appear older because the xenocrysts themselves would be old. A K-Ar analysis of impure fractions of the sample, as Austin’s were, is meaningless. Young-earth creationist ‘dating‘ of a Mt. The failure of Austin and Swenson to recognize obviously ancient minerals.
Helens, in southwestern Washington, was in some ways the queen of the Cascades Range. Beautifully symmetric, snow-capped, it had been called the Fujiyama of the Pacific Northwest. Scores of people flocked to St.
The conventional K-Ar dating method was applied to the dacite flow from the new lava dome at Mount St. Helens, Washington. Porphyritic dacite which solidified on the surface of the lava dome in gives a whole rock K-Ar ‘age’ of ± million years (Ma).
Helens is located in Washington State and is said by the U. Helens, then British Ambassador to Spain. Helens began to spew ash and steam, marking the first significant eruption in the conterminous United States since … The crown of the ash column rose to about 6, feet above the volcano. PDT, apparently in response to a magnitude 5. Helens suddenly began to collapse, triggering a rapid and tragic train of events that resulted in widespread devastation and the loss of 57 people, including volcanologist Johnston.

What an oasis of discovery for geologists, archeologists, anthropologists, or university groups! And time is winding down; already, due to the polar ice melting and rising ocean levels, a few Pacific islands have experienced flooding and erosion; larger lands have noted salt water seepage into their fresh water. But recently, many geologists and explorers have been quietly examining the evidence and have published their logical conclusions.
Johnstone of Liverpool University, in Introduction to Oceanography, says, “The 2, fathom sub-marine contour of Pacific and Atlantic Oceans affords a suggestion of representing outline of submerged areas.
Mount St. Helens erupted in , but rocks were dated up to million years old. ALL of the samples taken from volcanic eruptions of known times and dates are carefully collected and sent to the labs.
