A swell in geology is a domed area of considerable areal extent.[1]
According to Leser, it is also called a sill (geology), and is a gently arched landform of various orders of size in topographic, sub-glacial or sub-hydric geology. It may be as small as a rock formation in a river or may assume continental scale.[2]
