Until the mid-1970s, it was impossible to know when each of the flows occurred.However, as this video segment adapted from Flowing lava erases nearly everything in its path.Cannon-like, highly explosive eruptions in January and March 1974 threw out large quantities of ash as a column into the atmosphere, and as avalanches flowing down the cone’s sides.Blocks weighing up to 1,000 tonnes were hurled 100 m (330 feet).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.However, we do know Someone who was present when all the earth’s rocks formed—the Creator Himself.He has told us when that was, in His eyewitness account in the Bible’s first book, Genesis, so we know how old all the rocks are.

Because argon is a gas, it should escape to the atmosphere due to the intense heat of the lavas. All flows were typically made up of jumbled blocks of congealed lava, resulting in rough, jagged, clinkery surfaces (Figure 8).

Starved of the oxygen required for combustion, these bits of organic material are preserved inside the cooling lava.

When geologists find these artifacts, they can use them to date the lava flows that contain them.

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

However, Mt Ngauruhoe is an imposing, almost perfect cone that rises more than 1,000 metres (3,300 feet) above the surrounding landscape to an elevation of 2,291 m (7,500 feet) above sea level1 (Figure 3).
