After 30 years at the University of Minnesota, Dr. Osgood retired to Wooster, Ohio where he occasionally lectured at the College of Wooster and continued to write. He spent his summers in Montana with his wife on Alice Creek in the western part of that state, near Lewis and Clark Pass (Montana), until his death in 1983. His love of the West never abated; in an article published near the end of his life in the Western Historical Quarterly of the Western History Association entitled I Discover Western History, Osgood wrote As I drive westward, the words of the prophet Isaiah come to me, 'For ye shall go out with joy, and be led forth with peace; the mountains and the hills shall break forth before you into singing and all the trees of the field shall clap their hands'.
