Not many people live to leave a legacy. Arlen Allmon is one of the fortunate few. After graduating Ironton High School in 1950, he proudly served his country in the United States Navy during the Korean War as a Machinist's Mate from 1950 to 1954. He then returned home to earn his Bachelor's Degree from the University of Missouri - Columbia in 1958. He loved the outdoors and always told folks how lucky he was to have a vocation in Forestry that was more of an avocation. He was at home in the woods, taking in its splendor any time of the year, and took pride in caring for the natural world through his 31-year career with the Missouri Department of Conservation. He was a key contributor to the development and plotting of the Ozark Trail through Missouri. He was responsible for planting over 10 million trees, suppressing over 400 natural cover wildfires, and developing management plans for state lands throughout Missouri. He worked with the MDC during its most dynamic period of growth and was part of important campaigns throughout all divisions. These included assisting with efforts to restore populations of deer, Canada geese, and wild turkey; helping crusade for and win the 'Design for Conservation;' and working with Conservation Agents on undercover enforcement operations. He loved it all. Arlen was also a member of the Dardenne Presbyterian Church of Dardenne Prairie. As well as loving the outdoors and spending much of his time hiking and traveling, he enjoyed dabbling in photography and learning the history of the Western U.S. Arlen dearly loved his family and he will be missed greatly by all who knew and loved him in return. Services will be held at Dardenne Presbyterian Church, 7400 S. Outer Rd. 364 on March 23. Visitation will be from 11 a.m. to 12 p.m. with a Memorial Service to follow at 12 p.m. Memorials may be made in Arlen's name to The Gary Sinise Foundation, National Park Foundation, or Honor Flight of Columbia.
