…James Hutton, the father of modern geology and the understanding of deep time, was born.
Without his sharp observations on the geology around the Edinburgh area and the Scottish Highlands, we might never have learned that Earth was vastly older than previously thought. In 2005 a group of students from Lund University and I were graciously guided around the fantastic geology around Edinburgh by Professor Euan Clarkson, who told us many stories about the life and times of James Hutton. A truly wonderful excursion! 🙂
One of the localities was Siccar Point with “Hutton’s unconformity”, where Devonian Old Red Sandstone (345 million years old) overlie Silurian greywackes (425 million years old) with an angular unconformity (see above), which we visited during a rather grey day with very strong winds that almost blew us off the cliff.
Happy Birthday James Hutton!
