With the phrase (Omer) "came" (from the hill Cumorah) to a place which was called Ablom, by the seashore" (Ether 9:3), we get a possible implication that there was a sea "eastward" from the hill Cumorah and from the hill Shim. How far eastward we are not told. What the name of the sea was we are not told.
Ether 9:3 Omer came over and passed by the hill of Shim, and came over by the place where the Nephites were destroyed ([Illustration]): The two peaks of the Hill shim (right) and the Hill Ramah/Cumorah (left) on site in Veracruz, Mexico.
