The earliest Mumun features were usually located in low-lying narrow gulleys that were naturally swampy and fed by the local stream system.

Some Mumun paddies in flat areas were made of a series of squares and rectangles separated by bunds approximately 10 cm in height, while terraced paddies consisted of long irregularly shapes that followed natural contours of the land at various levels ( Bale 2001 ; Kwak 2001 ).
