The best “proof” for millions of years of earth history in most people’s minds is radioisotope dating. But is the method all it’s cracked up to be? Can we really trust it? The lava dome at Mount St. Helens provides a rare opportunity for putting radioisotope dating to the test.
In August of 1993, I had the exciting privilege of accompanying geologist Dr. Steven Austin and others from the Institute for Creation Research on a climb into the crater of Mount St. Helens to view the lava dome. It was one of those experiences that was well worth every exhausting moment! The dome (Figure 1) sits like a small mountain (roughly 3/4 mile in length and 1000 feet high) directly over the volcanic vent, which is at the south end of the huge horseshoe-shaped crater blasted out of the mountain by the May 18, 1980 eruption.
