Native Americans used the survey area for hunting and fishing and had permanent dwelling sites. Two Native
American tribes were in constant conflict. The Dakota (Sioux) were being pushed from their home area by the Ojibwa (Chippewa) during the late
18th century and early 19th century. Burial mounds and artifacts can still be found. Some of the oldest remains of Native Americans were found
near Pelican Rapids, Minnesota. The remains, nicknamed Minnesota Girl, were dated at about 11,000 B.C. (Otter Tail County Historical Museum).
The first white men to enter the county were French and British fur traders. Efforts were made to set up trading posts on the Leaf Lakes and
Otter Tail Lake. In the late 19th century, most of the towns were built along the railroad lines. Lumber and agriculture were the major
industries in the county at that time. The pine and hardwood forests, transportation system, and markets were instrumental in the development
of Fergus Falls into a lumber center.
