East Leroy and Sonoma anchor this rural landscape in Calhoun County, where small agricultural settlements are connected by a dense grid of county roads such as M 66 and Division Dr. The terrain is defined by a complex drainage system featuring Nottawa Creek, Pine Creek, and Severence Creek, alongside several glacial kettle lakes like Graham Lake and Sonoma Lake. These water bodies and marshy lowlands suggest a landscape that has long dictated the placement of farms and local transport routes. Genealogy researchers will find several family-named burial grounds throughout the townships, including Morgan Cem, Mather-Voyce Cem, and Walker Cem. A significant area of interest is the Farm Service Agency Interest of Michigan, indicating specific land conservation or management roles in this part of the state.
