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.
This comes as a surprise to no one. Any good volcanologist or sedimentologist will be able to recognize volcaniclastic rocks in the rock record. In fact these types of deposits are quite common in the rock record, and are thousands of meters thick in places. For instance, there are the deeply-eroded remains of a large Cretaceous stratovolcano named the Sliderock Volcano not too far from where I live in south-central Montana. This is recognized as a stratovolcano by having the remains of a magma chamber in the center, and then volcaniclastic rocks dipping away from that central vent area in all directions. The mountain was probably the size of the larger Cascade Range volcanoes, such as Shasta or Rainier. The YEC claim that this entire complex volcano formed and eroded in a few weeks towards the end of the flood is mind-boggling.
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
Any method of dating samples is a popular topic of attack in the Young Earth Creationist front. After all, the age of the earth makes or breaks their case. A popular example among them is Mt. It was mentioned to me rather enthusiastically tonight that a pastor is doing a series on creationism. I was told that all methods of dating are false, and that rocks spewed from Mt.
