-Potassium-argon method: is a geologic dating method relying on the percentage of potassium in a specimen that has radioactively decayed to argon.

This method was used on samples from the Mount St. Helens disaster.

Dacite.(a fine grained rock light in color).was retrieved and analyzed by Geochron Laboratories of Cambridge, MA, a professional radioisotope dating laboratory. The laboratory was not told that the specimen was 10 years old from the lava dome at Mount St. Helens. 

The results ranged from 0.35-2.8 million years! It is conceivable solidification of magma does not reset the radioisotope clock to zero. It could be that some argon-40 is combined into newly formed minerals giving the aspect of significant age. It should also be noted that there is inconsistency between various samples taken from the same rock. 
   Many other examples of this method's inaccuracy abound. Why use it?
