The ESU Geology Museum has recently been renamed the Johnston Geology Museum in honor of Professor Paul Johnston for his 38 years of dedication to the Earth Sciences Department and the University as a whole. He was responsible for starting the museum and has been director, curator, collector and jack-of-all-trades for the museum since its inception. The image above shows Paul doing what he did best -- teach. He did not limit this combination of teaching and field trips to university classes. Paul led trips for such diverse groups as the ESU geology club, the Boy Scouts, Elderhostel, the Kansas Academy of Sciences, and the Kansas Earth Science Teachers Association. The museum is an enduring legacy of his dedication and will continue to help teach everyone who visits it long after his retirement.
