Speaker Information

Friday 11:00-12:00 Marie Takach Central Washington University

Marie is a western Pennsylvania native who is interested in studying the processes by which volcanic rocks form. Since there are no volcanoes in Pennsylvania, she fled to the west coast in 2016 to pursue graduate studies in geology, where she is currently a master’s student at Central Washington University. There, she studies the chemical compositions of volcanic rocks and minerals in order to gain insight into their formation and evolution. The title of her presentation will be Mt. Etna Volcano, Italy: A Historic Landmark And Volcanic Laboratory.

Friday 1:00-2:00 Melanie Swick Central Washington University

Melanie is a masters student at Central Washington University. She is studying geology with a focus on snow studies. She realized that geology had won her heart after she began studying glacial geology as an undergraduate at St. Lawrence University in New York State. After moving to the Pacific Northwest she realized she could combine her passion for geology with her passion for the outdoors. during her spare time she can be found in the mountains skiing, snowboarding, hiking, and rock climbing. The title of her presentation will be Partitioning the Contribution of Light Absorbing Aerosols Using a Novel Hyperspectral Microscopy Method.

Friday 2:00-3:00 Greg Carr North America Research Group

In 2015 he received the prestigious James Shea Award, a National Association of Geoscience Teachers Award which recognizes exceptional delivery of earth science content to the general public. Past Shea Award recipients include John McPhee, Jack Horner, Robert Ballard, and Stephen Jay Gould.

Nick is a tireless promoter of everything that has to do with the field of geology and is a master of taking complex concepts and making them understandable to the general public. His public field trips are attended by hundreds of people. For these he provides detailed geology maps and information that make the landscapes of Washington State come alive.

Sunday 11:00-12:00 Pat McMahan

Pat McMahan was born in Los Angeles, California in 1947. At the age of eight he met Professor Ade, a well know rockhound who collected in the 1930’s. He taught Pat how to cut, polish, distinguish the various rocks, document his collection, and prepare displays for shows. Pat focused on rocks until he was 12 years old then set the hobby aside until he was about 38 and had kids of his own. He got a guidebook and took his wife Kathy and two boys Scott and Chad to the desert camping and rock collecting. With Professor Ade’s influence Pat came to love sagenite and plume agate. Little did Professor Ade know that he was creating a life-long obsession for Pat.

Pat graduated from the University of Southern California in 1969. His major was business but he loved the earth sciences and studied geology, systematic botany and more. Upon graduation he worked in his family’s office furniture business and after 15 years opened his own retail stores in Santa Barbara and Ventura. Selling his business at age 42 and retiring, Pat has spent much of the past 30 years collecting agates.

His long years of intensive collecting resulted in the best and most comprehensive collection of sagenite and plume agate in the world. More than 8,000 polished agate specimens from over 550 locations are in his collection. Most of these agates have been collected in the field by Pat himself. He has spent considerable time digging on the Laguna and Coyamito Ranches with Gene Mueller from thegemshop.com. He has dug “Condor Agate” at over a dozen localities in Argentina and has collected in all 11 Western states in the U.S., also in Canada and Alaska.

In addition to plume, sagenite and dendritic agates, he has a collection of fine quality banded agates. He has displayed agates in rock shows in Europe and across the U.S. He has published articles in Rock and Gem Magazine and the German magazine Mineralien Welt, and is the author of a chapter on agates with inclusions in the authoritative book Agates II. Pat has just completed Agates, The Pat McMahan Collection. This is a comprehensive book of 500 pages which includes 1,250 beautiful color photos of agates from 300 agate deposits worldwide. It shows personal collecting stories, prospecting techniques, history of some locations and more.  His signed book will be available for viewing and purchase. http://agateswithinclusions.com.

Sunday 1:00-2:00 Bron Mayo The Wenas Mammoth Foundation

Bron and her husband Doug are the driving force behind the Wenas Mammoth Foundation and the dig site on their property that led to its formation. Construction of an access road led to the discovery of the partial skeleton of a regionally rare Columbian Mammoth which was excavated by researchers from Central Washington University over several summer dig seasons. Since then Bron and her husband have been tireless advocates for science education as it applies to the dig site. Their mobile museum has been toured by thousands of students and adults and their outreach presentations at area schools have been well received. Bron has designed several hands on activities for kids that have been showcased at the Central Washington State Fair and other events around the Yakima Valley. She is also a tireless writer of grant proposals, the success of which has led to the development of both the mobile museum and infrastructure at the dig site. Bron will be giving an overview of the Wenas Mammoth Project.

NOTE: Being that it is still February this slate of speakers may or may not change by show time. Stay tuned for updates or any changes.
