On May 18, , a tremendous landslide on the northern side of Mount St. Helens in Washington state uncapped a violent volcanic eruption, completely altering the surrounding landscape. It is the most studied volcano in history and has reshaped thinking regarding catastrophic earth processes. The Institute for Creation Research has studied the volcano over the past three decades, conducting research that has provided a suite of informative lessons with broad-ranging implications.
For example, the rapid outflow from the volcano caused massive amounts of sediment to fill in the entire valley adjacent to the mountain. And a dam breach of the snow-melt lake that had formed in the mountain’s crater caused a catastrophic flood that tore a gash through those fresh deposits from two years earlier.

‘Ages’ obtained for the lava dome of Mt St Helens
Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life. Some so-called creation scientists have attempted to show that radiometric dating does not work on theoretical grounds for example, Arndts and Overn ; Gill but such attempts invariably have fatal flaws see Dalrymple ; York and Dalrymple Other creationists have focused on instances in which radiometric dating seems to yield incorrect results.
In most instances, these efforts are flawed because the authors have misunderstood or misrepresented the data they attempt to analyze for example, Woodmorappe ; Morris HM ; Morris JD Only rarely does a creationist actually find an incorrect radiometric result Austin ; Rugg and Austin that has not already been revealed and discussed in the scientific literature.

Mount St Helens WARNING: Scientist reveals molten rock ‘rising FIVE about possible Mount St. Helens eruption is 15 years out of date.
Mount St. Helens is a volcano located in southwestern Washington state. For thousands of years, Mount St. Helens has alternated between times of explosive eruptions and long periods of relative calm. But on May 18, , after experiencing a couple of months of earthquake activity and weak volcanic flare-ups, Mount St. Helens erupted violently, decimating everything in its path.
The volcanic explosion claimed more than 50 lives, destroyed thousands of acres of land and wiped out entire animal and plant communities. It darkened skies for hundreds of miles, sent a huge ash cloud circling around the globe and dramatically changed the landscape of the mountain and its surrounding areas. Helens and the Cascade Range are a small part of the Ring of Fire, a zone of intense volcanic and seismic activity that surrounds the Pacific Ocean, stretching from the west coast of South America, northward through Central and North America to Alaska and the Aleutian Islands.

I’m skeptical that the defects and fractures in the orthopyroxenes and feldspars of Austin’s dacites could hold more excess argon per mineral volume than the relatively large open structures within the hornblendes Dickin, , p. Therefore, IF hypothesis 1 was the only factor influencing the dates of Austin’s samples, I would expect the hornblende-rich ‘fraction’ to provide an older date than the pyroxene- and feldspar-rich ‘fractions.
From the above discussions, we already know that hypothesis 2 is a likely explanation for Austin’s old dates.
2. Rocks from the Mt. St. Helens eruption were analyzed and measured to be thousands of years old. Was this predictable, or did this reveal a flaw in the dating.
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.

In there was a catastrophic explosion of the volcano which consisted of six explosive magmatic eruptions – May 18, May 25, June 12, July 22, August 7 and October 17, The present lava dome at Mount St. Helens is the third dome to form since the eruption, the first two having been blasted away by subsequent eruptions.
30 Years Later, the Lessons from Mount St. Helens
History – Mt. Mount St. 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.

How Old Is the Mount St. Helens Lava Dome?
In a geological context, composite volcanoes tend to form relatively quickly and do not last very long. Mt. St. Helens, for example, is made up of rock that is all.
Here I want to concentrate on another source of error, namely, processes that take place within magma chambers. To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating. Radiometric dating is largely done on rock that has formed from solidified lava. Lava properly called magma before it erupts fills large underground chambers called magma chambers. Most people are not aware of the many processes that take place in lava before it erupts and as it solidifies, processes that can have a tremendous influence on daughter to parent ratios.
Such processes can cause the daughter product to be enriched relative to the parent, which would make the rock look older, or cause the parent to be enriched relative to the daughter, which would make the rock look younger. This calls the whole radiometric dating scheme into serious question. Geologists assert that older dates are found deeper down in the geologic column, which they take as evidence that radiometric dating is giving true ages, since it is apparent that rocks that are deeper must be older.
But even if it is true that older radiometric dates are found lower down in the geologic column, which is open to question, this can potentially be explained by processes occurring in magma chambers which cause the lava erupting earlier to appear older than the lava erupting later. Lava erupting earlier would come from the top of the magma chamber, and lava erupting later would come from lower down.
