Scholars have been unable to identify the specific land route the Jaredites took to arrive at the ocean shore. As they made their way toward the ocean, they had barges that were used to cross smaller bodies of water—perhaps rivers, inland lakes, or seas (like the Caspian Sea). They eventually ended up somewhere on the coast of China or Korea, where they entered barges that took them across a very large body of water. The journey on the water was a long one—344 days—until they arrived at a landing place in their Promised Land. The ocean voyage was probably a longer trip than the inland route that they might have taken.
John L. Sorenson, a renown Mesoamerican scholar, has pointed out that if you throw a tennis shoe in the water off the coast of Korea or Japan and then let the Pacific current take its course, the shoe will wash ashore somewhere around El Salvador in about 340 days. Such are the currents of the ocean. This exact scenario was recently proven. Not too long ago, there was a container-load of Nike shoes on a ship that went down in a storm right off the coast of Japan. The container went to the bottom of the ocean and broke open. The shoes all popped up on top of the water and floated with the ocean currents. This story was in the news because there were hundreds of shoes that washed ashore in Central America. As a result, people were running along the shoreline picking up brand-new, brand-name shoes.
