Jeff DeFreest started flying early in life – logging his first hours in 1972 – but his flight training stalled until he was well into his career as a professional geologist with the US Forest Service (USFS). He worked in Idaho, Oregon, and Utah before transitioning to Alaska in 2001.
Before moving to Alaska, he had restarted his flight training and got an introduction to backcountry flying in the San Rafael Desert in Utah. He flew SuperCubs in Arizona on weekends, while studying to become a certified minerals examiner for the USFS. He earned his private pilot certificate in Alaska on the 99th anniversary of powered flight on December 17, 2002.
