Just found out about Don's passing. I worked with Don for over 10 years at ExxonMobil when he was doing regional geology. Don was a great mentor, colleague, gentleman, and above all the model for professional conduct. I want to pass on my deepest condolences. Don had (and still has) many friends in the technical ranks at ExxonMobil where he was greately respected.
