On March 23, 1806, Lewis and Clark began their journey back from the Pacific coast to the East to report on their expedition. The winter had been brutally cold and wet. They had traveled about 4,000 miles from St. Louis and had been gone almost two years.
Lewis and Clark thought they could avoid the trip back over land by getting on a merchant ship but there were none to be found. And so, without much food or supplies, they began the trek back. In six months, they arrived in St. Louis.
