The scenario advanced by Heartland and Great Lakes setting advocates considers that events at Jerusalem and teetering family relations, had made it unwise for Lehi's family to flee to the populated Mediterranean coast. The prospect of sailing to another land of promise by way of the Mediterranean was therefore out of the question. In an effort to avoid adversaries, Lehi's family fled into the southern desert, eventually arriving at an isolated location on the southeastern shore of the Arabian Peninsula. There they constructed a ship. Currents and seasonal winds at this location could have carried them to the coast of Africa and southward. There may have been more than thirty individuals in Lehi's company at this point. They would have had only so much stowage aboard their vessel for food and fresh water. The preferred route to the land of promise would have been one that would stay within easy reach of a coastline (food and much needed fresh water) most of the voyage. After "many days" at sea, they confronted a fearsome tempest (proposed to have occurred near Africa's horn). Thereafter, with enough fresh water and supplies stored on board, they crossed over to the Western Hemisphere along the shorter and more direct route between the Old World and the New World – assisted by the prevailing winds and equatorial currents of the Atlantic. Still aided by currents and winds, they sailed along American coasts and island chains until they arrived near the Gulf of Mexico. At this point the opinions of Olive and May diverge as to the final landing of Lehi.
