Lincoln Hills
From Wikipedia, the free encyclopedia
The Lincoln Hills extend along the Mississippi River, starting about 40 miles northwest of St. Louis and extending to Hannibal, located in Lincoln, Pike, Ralls and Marion counties. The Lincoln Hills, locally referred to as 'knobs', may have partially escaped glaciation and resemble the rugged and forested hills of the Ozarks, rather than the rolling plains of northern Missouri. The limestone bedrock has formed bluffs, glades, caves, springs, and sinkholes.
