Guest Speaker Linda Sue Baugh.
Guest Speaker at the Skokie Valley Rotary Weekly Meeting of October 18, 2016 was Linda Sue Baugh.  She wonderfully demonstrated the club assembly, with the aid of a slide-show, how she and a few other friends traveled around the world to find geological stone/mineral formations. She also had a book for sale, full of breath-taking pictures.
Below are questions people usually ask:
What made you want to document the world's oldest rock and mineral sites?

No one event inspired this work. Instead, the project had several sources. One source was the blizzard of global media and information that arose at the turn of the 21st century. This provoked the question: What was authentic experience in our lives anymore? Also, as more open land disappeared in the face of urban development, it seemed the idea of "nature" was becoming increasingly abstract.
We wondered what Earth might have been like before humanity arose. If we could travel to places that echoed that early time, devoid of human voices, what would we experience? It was then that we conceived of the project to journey to the world's oldest sites. The sites have been studied scientifically, but our goal was to see them as artists. We wanted to arrive with few preconceptions, simply to listen. We had no idea what was waiting for us, or that we would travel so far, or that eventually we would found a company based on our work. 
How do you know where the oldest sites are?

We talked with geologists, who gave us a list of the oldest sites that have been scientifically dated. The list included places in Western Australia, Canada, Greenland, South Africa, the United States, and Brazil. Other sites in Asia and Russia have also been identified. We started with the site of the oldest minerals on Earth, found at Mt. Narryer and Jack Hills in Western Australia.
Do you have a background in geology or photography?

At our photography show in Vevey, Switzerland, we were asked by one person, "Are you geologsts?" "No," we answered, "although we've had a life-long interest in stones and Earth history. And we've interviewed geologists for the project."  "Are you photographers then?"  "Not exactly," we said. "We let the places more or less dictate when and how to take the photographs." 
At this point, our questioner's face lit up in sudden understanding. "Ah, then you are artists!"
That moment affirmed our calling and our task. This journey has meant not only traveling to ancient places; it has meant blending two ways of knowing--scientific fact and artistic response--to convey the mystery of what we encountered.
