Greenfield Township was organized on February 9, 1888, according to the files of commissioners' Proceedings at the Court House.

The Township records go back only to February 26, 1895, as there seems to have been a fire and all previous records were lost. The minutes of the meeting on February 26, 1895 indicate that C. E. Skarie was the Chairman of the Board of Supervisors and other members named were Nels Hemmingson and Ed Olson. A. M. Sinclair was the clerk. No treasurer was named in the minutes.

Mr. Carl A. Nelson was elected to the office of Township clerk in March 1899. He served continuously until 1954, thereby holding the same office for 55 years - a record that has not been broken.

The Township name was suggested by Nels Hemmingson after a place where the same people had lived in Minnesota. Since this Township has Bald Hill Creek running across it full length, it probably qualified for the name on its own account. Two railroads also cross the Township full length, the Northern Pacific north and south, and the Great Northern Surrey Cut-off east and west.
