Omer’s Ablom Tent is the tent Omer pitched at Ablom, a place “by the seashore.” Omer reached Ablom after departing the land with his family and traveling many days (Ether 9:3).
Omer passed the hill of Shim and the place where the Nephites were destroyed before traveling eastward to Ablom. His sons, daughters, and household also pitched tents there, except Jared and his family (Ether 9:3).
