Editing Kansas (section)

===Topography===

The western two-thirds of the state, lying in the [[Great Plains|great central plain]] of the United States, has a generally flat or undulating surface, while the eastern third has many hills and forests. The land gradually rises from east to west; its altitude ranges from {{convert|684|ft|m|sp=us|abbr=on}} along the [[Verdigris River]] at [[Coffeyville, Kansas|Coffeyville]] in [[Montgomery County, Kansas|Montgomery County]], to {{convert|4039|ft|m|sp=us|abbr=on}} at [[Mount Sunflower]], {{convert|0.5|mi|km|abbr=off|sp=us}} from the Colorado border, in [[Wallace County, Kansas|Wallace County]]. It is a common misconception that Kansas is the flattest state in the nation—in 2003, a tongue-in-cheek study famously declared the state "flatter than a pancake".<ref>{{cite web |url = http://improbable.com/airchives/paperair/volume9/v9i3/kansas.html |title = Kansas Is Flatter Than a Pancake |publisher = Improbable.com |access-date = July 31, 2010 |url-status = dead |archive-url = https://web.archive.org/web/20100730133707/http://www.improbable.com/airchives/paperair/volume9/v9i3/kansas.html |archive-date = July 30, 2010}}</ref> In fact, Kansas has a maximum topographic relief of {{convert|3360|ft|m|sp=us|abbr=on}},<ref>{{cite web |url = https://www.infoplease.com/world/united-states-geography/highest-lowest-and-mean-elevations-united-states |title = Highest, Lowest, and Mean Elevations in the United States |publisher = infoplease.com |access-date = May 20, 2018 |archive-date = May 21, 2018 |archive-url = https://web.archive.org/web/20180521191553/https://www.infoplease.com/world/united-states-geography/highest-lowest-and-mean-elevations-united-states |url-status = live }}</ref> making it the 23rd flattest U.S. state measured by maximum relief.<ref>{{cite web |url = http://www.geotimes.org/oct03/NN_pancake.html |archive-url = https://web.archive.org/web/20040124015708/http://www.geotimes.org/oct03/NN_pancake.html |url-status = dead |archive-date = January 24, 2004 |title = Fracas over Kansas pancake flap |publisher = Geotimes.org |access-date = July 31, 2010 }}</ref>
