|The Acre Family Bam is an example of a modified Transverse-crib barn. Transverse-crib barns evolved as distinct folk bam in southern Appalachia during the 1810s (Jordan, 1998). The Transverse-crib bam is the single most common bam type in the Upland South. They are also the most common bam type in western Oklahoma, including Blaine County, although there are many variations in size and detail (Bays, 2011). The traditional floor plan of a Transverse-crib bam is simple: a central aisle running parallel to the ridgeline flanked on both sides by a row of three or more square cribs, which-individually or in combination-serve as stalls, granaries, or storage space. A haymow or loft for hay and/or grain storage is above ground level. A wagon door is in one or both gable ends of the bam.
