Retired Col. Amos Mathews served as the district engineer from 1970-1973. He is one of 26 soldiers to have served as the Alaska District commander during the 68-year history of the organization. His image is displayed among a group of leaders that are now pillars of Corps engineering history in Alaska. An ecstatic Col. Christopher Lestochi, the current district commander, hosted Mathews during a visit to the headquarters building at Joint Base Elmendorf-Richardson June 9.
