How Old Is the Mount St. Helens Lava Dome?

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. To this day, the resulting steep-sided canyon walls can be seen, 2 showing that horizontal sediment layers hundreds of feet thick were formed within hours during the eruption. This sparks the question: what other layered sedimentary rocks in earth’s crust were formed rapidly?

‘Ages’ obtained for the lava dome of Mt St Helens

History – Mt. Lateral “blast” Within a few seconds after the onset and mobilization of the debris avalanche, the climactic eruptions of May 18 began as the sudden unloading of much of the volcano’s north flank abruptly released the pent-up pressure of the volcanic system. The sudden removal of the upper part of the volcano by the landslides triggered the almost instantaneous expansion explosion of high temperature-high pressure steam present in cracks and voids in the volcano and of gases dissolved in the magma that caused the bulge of the cryptodome.

Mount St. Helens. We received a You also mentioned Mount St. Helen, now I ask, how did this mountain produce stratified rock? Now if during We would rather see them dated at 20 years old because that is the correct date. Furthermore.

On March 27, , a series of volcanic explosions and pyroclastic flows began at Mount St. It initiated as a series of phreatic blasts from the summit then escalated on May 18, , as a major explosive eruption. The eruption, which had a Volcanic Explosivity Index of 5, was the most significant to occur in the contiguous 48 U. The eruption was preceded by a two-month series of earthquakes and steam -venting episodes, caused by an injection of magma at shallow depth below the volcano that created a large bulge and a fracture system on the mountain’s north slope.

This allowed the partly molten, high-pressure gas- and steam -rich rock in the volcano to suddenly explode northwards toward Spirit Lake in a hot mix of lava and pulverized older rock, overtaking the avalanching face. Less severe outbursts continued into the next day, only to be followed by other large, but not as destructive, eruptions later that year.

Thermal energy released during the eruption was equal to 26 megatons of TNT. Approximately 57 people were killed directly, including innkeeper Harry R. Helens was left with a crater on its north side. At the time of the eruption, the summit of the volcano was owned by the Burlington Northern Railroad , but afterward the land passed to the United States Forest Service.

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. The creationist approach of focusing on examples where radiometric dating yields incorrect results is a curious one for two reasons.

1980 eruption of Mount St. Helens

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.

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.

At a. PDT, Mount St. Helens , a volcanic peak in southwestern Washington , suffers a massive eruption, killing 57 people and devastating some square miles of wilderness. Helens is located in the Cascade Range and stood 9, feet before its eruption. The volcano has erupted periodically during the last 4, years, and the last active period was between and On March 20, , noticeable volcanic activity began again with a series of earth tremors centered on the ground just beneath the north flank of the mountain.

These earthquakes escalated, and on March 27 a minor eruption occurred, and Mount St. Helens began emitting steam and ash through its crater and vents.

Mount St. Helens Eruption: Facts & Information

Introduction: Rocks and fossils do not come with dates on them. In fact, the very concept of strata representing long ages does not come from the rock strata themselves. That concept began with eighteenth-century French naturalist Georges Cuvier, picked up steam with Charles Lyell, and it has been in vogue ever since. This is despite the fact that it causes more problems for interpreting rock strata than it solves.

And today we know through lab experiments and natural disasters such as the eruption of Mt.

Because radiometric dating utterly refutes their biblical interpretations, young-Earth creationists YECs are desperate to undermine the reality of these methods.
