Mount Steā¦Mount Sterling is a census-designated place in Van Buren County, Iowa, United States. The population was 33 at the 2020 census. Mount Sterling was first settled in the late 1830s when George and Horace Wood established a sawmill and corn-cracker to serve the small farms of southern Van Buren County and the northern portion of nearby Scotland County, Missouri. Within a decade the Woods were joined by several other businesses. At first, the small village had no official name and was often referred to as "Dogtown" by the early residents. This came from the fact that nearly every farmer who came to the mill brought at least two or three dogs along, and also from the fact that Horace Wood had three hounds who loved to devour the corn meal as it left the grinder.
