Plains of Agosh
From MormonWiki
The Plains of Agosh are a geographical location in the Book of Mormon. In the Book of Ether, the plains are the location where Lib and his armies battled Coriantumr for reign over the Jaredites. Coriantumr and his armies had fled before Lib from the seashore through the Wilderness of Akish until Lib caught up to him on the plains. The battle continued on the plains until Coriantumr succeeding in slaying Lib. Lib's brother, Shiz, however, continued the fight until Coriantumr was force to flee from the plains. (See Ether 14:15–16.)
The Book of Mormon Onomasticon created through Brigham Young University provides the etymology of the geographical name Agosh [1].
