However, it is well-known that if a radiometric “date” contradicts a fossil-derived (evolutionary) age, the date is discarded as erroneous.See Lubenow, M., The Pigs Took It All, Creation 17(3):36–38, 1995. note, this Creation magazine article by Dr Snelling is based on his technical paper21, which has far more detail about research methods and answers to possible criticisms than was possible in Creation magazine.Geochron is a respected commercial laboratory, the K–Ar lab manager having a Ph. However, the samples were described as probably young with very little argon in them so as to ensure extra care was taken during the analytical work. This violates assumption (1) of radioactive dating, and so the K–Ar method fails the test.This same failure is also known to occur in many other rocks, including both recent volcanics18and ancient crustal rocks.19 The radioactive potassium-argon dating method has been demonstrated to fail on 1949, 1954, and 1975 lava flows at Mt Ngauruhoe, New Zealand, in spite of the quality of the laboratory’s K–Ar analytical work.Argon gas, brought up from deep inside the earth within the molten rock, was already present in the lavas when they cooled.

It is not as well publicized as its larger close neighbour MT Ruapehu, which has erupted briefly several times in the last five years.

Mt Ngauruhoe is thought to have been active for at least 2,500 years, with more than 70 eruptive periods since 1839, when European settlers first recorded a steam eruption.2 Of course, before that, the Maoris witnessed many eruptions from the mountain.
