Book of Mormon lands were made up of two large geographical areas arranged north (Land Northward) to south (Land Southward) connected by a smaller one (Narrow Neck of Land) along the west. Their lands were bordered on the east (Sea East) and west (Sea West) by “seas” with the northern area (Land Northward) bordered by a sea on its north (Sea North) and south (Sea South), with sub-areas within the larger.
The Land Northward had a unique extension east of the Sea East called Cumorah.
