Origin of the Drummond Flat, Garfield County, Oklahoma

Near Drummond, Okla,. in Tps. 21 and 22 N., R. 8 W., Turkey Creek crosses an extensive alluvial flat that is disproportionately large for the stream. Furthermore, this flat or basin is not long and narrow like other valley bottoms in the area but is roughly oval, being about 6 miles long and 3 miles wide. The basin was studied by the writer in the summer of 1950 during an investigation of the ground-water resources of the ter· race deposits lying along the northeast side of the Cimarron River In Alfalfa, Major, Garfield, and Kingfisher Counties. Turkey Creek enters the basin flowing southward and midway across changes its course abruptly and flows northeastward for 2% miles before bending sharply to the east and leaving the basin. A northward flowing barbed tributary joIns the main stream at the point where it bends sharply toward the northeast; its course, if reversed, would be the logical continuation of the maIn stream.
