Editing Geauga County, Ohio (section)

===Drainage system===
The [[geography]] of Geauga County was radically changed by [[Illinoian glaciation|Illinoian]] and [[Wisconsinan glaciation]], which is evident in the deranged [[Drainage system (geomorphology)|drainage system]], landscape change, and [[Till|glacial till]]. The [[headwater]]s of three [[river|watercourses]] in the [[Lake Erie]] [[drainage basin|basin]] are in Geauga County. These include the [[Cuyahoga River]], [[Chagrin River]], and [[Grand River (Ohio)|Grand River]]. Portions of all three are designated Ohio Scenic Rivers.<ref>{{Cite web |title=Scenic Rivers |url=http://www.dnr.state.oh.us/tabid/985/Default.aspx |access-date=August 28, 2011 |website=Ohio Scenic Rivers Program |publisher=Ohio Dept of Natural Resources (ODNR) |archive-date=August 27, 2011 |archive-url=https://web.archive.org/web/20110827071715/http://www.dnr.state.oh.us/tabid/985/default.aspx |url-status=dead }}</ref>
