Oatman Flat, is a flat, south of Oatman Mountain, on the south bank of the Gila River and north of the mouth of Wild Horse Canyon in Maricopa County, Arizona. The flat was named for the Oatman family that was massacred in their camp on the bluff overlooking the flat in 1851. They were later buried there along the Southern Emigrant Trail overlooking the flat that bears their name. What became known as Oatman Grave 33°00′15″N 113°09′23″W, on the flat below is a memorial and not the grave site.
