Jim Magnuson:

For author Jim Magnuson, rockhounding is not only a hobby, but it’s also 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 the willingness to follow the road less traveled in order to find unique or rare kinds of rocks. Jim also enjoys sharing his passion through writing, both creatively and from a practically oriented process perspective. 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 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.
