May 8 @ 6:00 pm - 7:30 pm

Lake Superior Agate Origins, Classification and Prospecting
This is a three-part presentation focused on Lake Superior Agates. Part one provides a high-level summary of the geological events that led to the formation of agates, a bit of agate chemistry, and the glacial activities that led to the broad distribution of Lake Superior Agates. Part two takes the audience on an inside and up-close tour of the incredible diversity of agate types and some possible formation theories. This second part of the presentation is accompanied by colorful and detailed photographs of multiple specimens for each type of agate. Part three will instruct the audience on how to hunt for and identify Lake Superior Agates and the many imposters that one might confuse with agates because of corresponding colors or features. The third part of the presentation provides critical tips for prospecting and photographs of rough agates and agate imposters. You could give a lifetime to hunting for and studying our amazing Lake Superior Agates; there is important research and discovery still waiting to be done!

  • Part 2 – Exploration of the diverse family of Lake Superior Agate Types and related Formation Theories – 21 mins
  • Part 3 – Lake Superior Agate Prospecting, Hunting and Identification – 34 mins

Jim Magnuson Biography
Rock hounding is more than a hobby for author Jim Magnuson, it’s a serious and rewarding avocation that
helps him connect with nature. He has been an avid hunter and student of various gems, minerals and fossils
since his childhood, when he first began to hunt for stones in his native state of Illinois. These experiences
taught Jim the importance of persistence and willingness to follow the road less traveled for more unique or
rare kinds of rocks. Jim also enjoys sharing his passion through researching and writing both creatively, and
from a practically oriented process orientation. Because of Jim’s in-depth knowledge, he is frequently called
upon to present to groups such as rock and mineral clubs, geological societies and educational institutions that
focus on outdoor and environmental interests. In addition to Jim’s passion for prospecting and hunting he also
likes to perform various lapidary arts with the stones that he finds, and he has a small business of making and
selling custom polished stones and jewelry pieces. Finally, Jim enjoys creating photographic illustrations that
are up close and personal for prospecting, hunting and lapidary work. Jim was a photographer for his high
school and college newspapers and yearbooks where he focused on student activities that created
perspectives on campus life. This experience has helped Jim capture unique and compelling photographic
images for modern day gem and mineral prospecting.

Jim has authored seven books with worldwide sales of over 70,000 copies; the list of publications is below:

  • The Storied Agate– A light-hearted photographic expose with stunning natural photographic images of
    Lake Superior Agates and stories about the hunting experience
