The family's poor finances, due to years of bad weather on the farm and a bad corn harvest in 1921, caused them to move to a new farm in [[Burdett, Kansas]] in 1922.<ref>{{Cite book |last=Levy |first=David H. |url=https://archive.org/details/clydetombaughdis0000levy_y9k6/page/20/mode/2up |title=Clyde Tombaugh: discoverer of planet Pluto |publisher=University of Arizona Press |year=1991 |location=Tucson, Arizona |publication-date=1991 |pages=20 |isbn=978-0-8165-1148-8 |via=Internet Archive}}</ref><ref>{{Cite web |last=O'Hara |first=Elva R. |date=2006–2007 |title=Clyde W.
