At approximately four metres (13 feet) thick, the basalt flow is relatively thin, Since the tree trunks were engulfed at the bottom of the flow, cooling may have been immediate, with any water present in the wood aiding extremely rapid encapsulation and thus preservation.
The local geological context makes the basalt flow approximately ‘30 million years old’, in keeping with other basalt flows in the region all regarded as of Tertiary age (in the conventional terminology).
James Hutton, a physician-farmer and one of the founders of the science of geology, wrote in 1788, “The result, therefore, of our present inquiry is, that we find no vestige of a beginning, — no prospect of an end.” Although this may now sound like an overstatement, it nicely expresses the tremendous intellectual leap required when geologic time was finally and forever severed from the artificial limits imposed by the length of the human lifetime.
By the mid- to late 1800s, geologists, physicists, and chemists were searching for ways to quantify the age of the Earth.

On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.
After digging through the thin surface sands and clays, followed by basalt, 21 metres (almost 69 feet) down they found pieces of wood entombed in the bottom basalt flow.1 Below the basalt were layers of claystone, siltstone, and sandstone with interbedded coal seams.2 The wood was in three states—ash, charred, and intact.1 Those on-site at the time speculated that there had been two distinct trees, partly standing, still organic in nature, and thus not petrified.
Until the 18th century, this question was principally in the hands of theologians, who based their calculations on biblical chronology.The latest high-tech equipment permits reliable results to be obtained even with microscopic samples.
