The geological forces that created The Three Sisters are revealed in Paul Gorjan’s book, Geology of the Blue Mountains: Tourist Guide. Thebook was launched at Leura Uniting Church on August 11.
I have a background in geology, so obviously I was interested in rocks around here, they are a big attraction.
His book offered insight into the science of valleys in the landscape.
As Gorjan writes: “The Three Sisters were formed by the same processes that formed the rest of the Jamison Valley; softer layers of clay have been eroded and the harder sandstone on top has been eroded. is tilted and then detached along the parting lines. ”
“I moved here four years ago,” he says. “I have a background in geology, so obviously I was interested in the rocks around here, they are a big attraction … a lot of tourists come … whether they know it or not, to see the geology.
“I couldn’t find any books available,” he added.
“I have found a few technical reports but they are not readable by the average person.”
Mr. Gorjan has pursued a career as a researcher in earth sciences. He received a post-doctoral fellowship from the Japanese Society for the Promotion of Science to work on the study of mass extinctions at Tohoku University. He also worked as a research scientist at the University of Washington in St. Louis.
Mr. Gorjan’s talents also extend to art. He was a finalist for the Gallipoli Art Prize in 2018 and produced the drawings for the book.
“For me to learn is to consolidate my knowledge,” he said.
