Page 16, bottom paragraph, pretty much confirms the location of Little River Town.
The road had proved rough and rocky, shattering the wagons and breaking king-bolts. One broken wagon was left behind for repairs. The distance from the last camp is but ten miles. Dr. Bigelow, Mr. Marcou, and some others made a detour of about a mile to the Canadian; and, crossing to the opposite side, visited the flourishing settlement and trading post called Little River. It is pleasantly situated upon the banks of the river where a stream bearing the same name as the town flows into the Canadian. Some interesting collections were made there. Fossil shells were found belonging to strata below the coal formation. In the vicinity are fragments of several Indian tribes. The "Quapois," according to Shawnee authority, are the remnant of a tribe formerly from Mississippi; but- for some time they have lived a roving life, and lately moved hither from the West.
