Briggs Hill is a mountain summit in the far southeastern corner of Highland Plantation and its base apparently runs across the plantation border into Lexington Township.

Briggs Hill climbs to 1,952 feet (595 meters) above sea level.

He, wife Susanna Cottle, and children resided on the hill in the early 1840s, finally leaving the stony farm in 1846 to travel westward (locating permanently in Willow Creek Township, Lee County, Illinois).

33.3% of all households were made up of individuals, and 29.2% had someone living alone who was 65 years of age or older.

There were 23.5% of families and 34.8% of the population living below the poverty line, including 56.5% of under eighteens and 25.0% of those over 64.
