Once settled, Cameahwait told Lewis the news he and Clark had been expecting: there was no all water route in which the expedition could take to reach the Pacific Ocean. The main reason for Lewis and Clark's worry was the Bitterroot Mountains. Lewis knew that if the Shoshone would not trade with his group; the expedition would fail. He decided that Clark and the others needed to know the situation, so Lewis, Cameahwait, and their men journeyed to where Clark and the others had made camp (Shoshone, PBS - 2005). While the captains and the chiefs began exchanging words through the communication line, Sacagawea realized that not only were these men from her home tribe; but Chief Cameahwait was her brother! The reunion of the two Shoshone people was very heart warming. After the reunion and the communications were over, the expedition was able trade some gifts for the horses they needed (Sacagawea, PBS - 2005).
