Remembering John Erwin

We are sad to pass on the news of the death of John Erwin on Thursday October 3, 2013.

John worked as a geophysicist for the Nevada Bureau of Mines and Geology for many years. Some of the publications that he wrote while at the Bureau are listed below.

A Celebration of Life service was held October 25, 2013 in Reno, Nevada, followed by a Military Internment Service at Mountain View Cemetery.
