We're happy to announce this year's line-up of Guest Speakers:

1 p.m. Saturday -- “Minerals from the Carbonate Rocks of the American Midwest”  Terry E. Huizing

A consulting editor of Rocks & Minerals magazine, is Adjunct Curator of Mineralogy at the Cincinnati Museum Center and focuses his personal collecting activities on calcite, pseudomorphs, and minerals from the American Midwest. Minerals found in the carbonate rocks of the American Midwest are well crystallized, beautiful, and abundant. Spectacular crystals occur in a wide range of habits, color, and association with other minerals. Collectible minerals from the Midwest occur at mines located in Mississippi Valley-Type deposits, at limestone quarries, and within geodes. The talk will feature a great number of photos of the mineral species found at these occurrences from the sixteen states of the American Midwest.

3 p.m. Saturday -- “A Paleontologist Looks at the Jurassic Park Movies”  Dale Gnidovec

Curator of the Orton Geological Museum on the Ohio State University campus.  The dinosaurs and other prehistoric animals in the Jurassic Park films are very lifelike, but how scientifically accurate are they?  This talk discusses what the filmmakers got right and what they got wrong.


2 p.m. Sunday --  “Seeking the ‘holey’ land of minerals”  Dr. Nelson Shaffer

Adjunct Professor, Indiana University-Purdue University Indianapolis and President, Nannovations. Large, perfect crystals need space to grow well. Vugs, solution cavities, mirolitic cavities,  geodes, even caves provide appropriate spaces. We shall look at holes, their kinds, origins, and implications to mineral collecting and some examples of fine minerals.
