209148 Dustindeford           Discovered 2003 Sept. 27 by the Sloan Digital Sky Survey at Apache Point.
Dustin DeFord (1989-2013) was one of the 19 elite Prescott's Granite Mountain Hotshot firefighters who lost their lives battling a blaze on a ridge in Yarnell, AZ. Crews such as the Hotshots are connected to astronomy through their brave efforts to protect forests and the observatories within them from fire threats.
