Buffalo Flats Cemetery lies five miles east of Ainsworth on Highway 20, then two miles north and a mile east, on the south-east corner of the intersection, in Brown County, Nebraska. It is also recorded as Pleasant Prairie Cemetery. It was laid out in 1883 as Pleasant Prairie Cemetery and renamed Buffalo Flats in 1972. Find a Grave gives the legal description as the north-west quarter of the north-west quarter of Section 13, Township 30, Range 21. Find a Grave holds 83 memorials for it, which is a record of what has been photographed and indexed rather than a count of everyone buried there.
