Heiken, Grant

After completing his Ph.D. at the University of California in Santa Barbara in 1972, Grant Heiken (heiken@whidbey.com) worked for NASA’s Apollo Program as a geology instructor and as a researcher on lunar surface processes. In 1975, he and his wife moved to the Los Alamos Scientific Laboratory in New Mexico, where he worked on geothermal exploration and development, volcanic hazard analysis, the uses of volcanic rocks, basic research on explosive volcanism, continental scientific drilling, and integrated urban science. He has co-written or edited 11 books. He retired in 2003 and moved to Freeland on Whidbey Island, Washington, with his wife Jody, who is a scientific editor. Grant volunteers for several service organizations, is on the board of the Whidbey-Camano Land Trust and is on the Island County water-resources advisory committee.

Grant’s March 2014 talk was based on his 2005 book The Seven Hills of Rome—A Geological Tour of the Eternal City” (G. Heiken, R. Funiciello, R., and D. De Rita, Princeton University Press, Princeton, 288 p). (Updated 2021)

In his off time, Terry is a marathon-style wilderness runner and avid hiker.  He is a mineral collector, a hobby fostered by his father from an early age. Terry has visited mining communities and mineral localities across the Americas, and has written extensively on various aspects of mineralogy for amateurs. He is the author of the popular mineral book Collecting Arizona. As you can suspect, Gold is one of his favorite minerals.
