Symposium 2021 – Minerals of Africa

We know that everyone would love to get together in Kelso next month for a live symposium, but that is just not the world we live in right now. So, this year’s symposium will be in the same Zoom format as last year. This worked to our benefit for this year’s theme: Minerals of Africa! We will have six talks, all presented on Saturday, October 16, 2021. Five talks will be on our Africa theme, and one will be local to the Pacific Northwest. Bryan Swoboda will be working with our speakers to record their talks and will apply his Blue Cap Productions magic to give them the professional polish that he is famous for. We will send a detailed schedule and Zoom instructions in advance, but we expect the start time to be 11 AM, Pacific Time.

The symposium will be presented via the Zoom platform so that all current members of PNWFM and guests will be able to join in. You will be able to ask questions of the speakers via a chat feature. There will be no registration fee for this virtual symposium.

DANGERS IN LONG GRASS: Mineral Collecting in the Republic of the Congo
Demetrius Pohl has been collecting minerals ever since, when, as a young boy on a camping trip with his family to the tungsten and moly mining areas of New England in New South Wales, Australia, he found a topaz crystal in Oban creek. He still has it.  After a false start in architecture, he switched to geology earning a Ph.D. from Stanford in geochemistry. His career yo-yoed between industry and academia with a stint as associate curator at the American Museum of Natural History, and teaching at Columbia, but most of his career was spent in mineral exploration in Australia, South America, and Africa. With college friends he started his own mineral exploration company focusing on Africa and South America. Fortunately, this venture was sold after more than 20 years and some successes, to some optimistic investors in London and he is now retired, restoring old houses, tending his mineral collection, and trying to travel with his wife, Chris.

Rocks, Minerals & Geology of the Pacific Northwest
Leslie Moclock (presenter) and Jacob Selander (co-author). PNWFM members know Leslie Moclock for her museum curatorship and displays and presentations at our last few symposia.

Many of you know that she was working on a new book, and it has arrived! In “Rocks, Minerals, and Geology of the Pacific Northwest” she and co-author Jacob Selander present the minerals and geology of our little corner of the planet in a fresh and geologically interesting way:
