***Special Presentation ***

New Hampshire Originals! Type Locality Minerals from The Granite Statewith Paul Brandes

Examples of beryl – New Hampshire’s state mineral

New Hampshire has a long history of mining and mineral wealth. According to the web site, over 360 different minerals can be found at the various mines that dot the state. Out of those, just eighteen are known as “type-locality” minerals; minerals that were first discovered and named in New Hampshire. Join geologist and author Paul Brandes as he describes the history of these minerals, as well as the process by which a new mineral is introduced to the world.

Join Paul Saturday, June 22 at 1 PM in the auditorium. Admission is free. Don’t miss it!

Meet Paul Brandes

Paul Brandes could be called a “jack of all trades” geologist of sorts. He was introduced to geology and mineral collecting at a very early age, having grown up on the Keweenaw Peninsula of Upper Michigan (Copper Country) digging up mineral specimens and researching the rich mining history of the area. He attended and graduated with degrees in geology from the New Mexico Institute of Mining and Technology and Michigan Technological University. Since graduation, he has worked as an exploration geologist, a geology/mining consultant, an environmental enforcement officer, and most currently as a professor of earth and environmental science at a community college. He is also an award-winning photographer, a best-selling author, a member of the management team, and on the Board of Directors of the Hudson Institute of Mineralogy. In what free time he has, Paul enjoys cooking, toying with classic cars, spending time with his cats, and traveling the world with his geologist wife Nathalie in search of new and exciting places to study geology and obtain minerals to add to their collection.
