Editing Stockton, Illinois (section)

==Geology==
Stockton is not part of the [[Driftless Area]], but is the first municipality found outside of it, coming from western [[Jo Daviess County]]. One climbs out of the valley of the [[Upper Mississippi River]] and finds a high point in Stockton.

The village water tower sits on a ridge at elevation {{convert|1,105|ft|m|abbr=on}}<ref name="watertower" /> that rises to {{convert|1,120|ft|m|abbr=on}} to the west at the village limits. To the northwest the same ridge line continues where U.S. Route 20 crests at {{convert|1,077|ft|m|abbr=on}} just to the west. This ridge line continues for 3 miles to the northwest to Benton Mound ({{convert|1,204|ft|m|abbr=on|disp=semicolon}} ), the second highest peak in Illinois.<ref name="BentonMound">{{cite web |url=https://peakvisor.com/peak/benton-mound.html |title=Benton Mound, PeakAdvisor.com |website=Peak Advisor |access-date=June 25, 2022}}</ref>
