Sacagawea was the one who helped Lewis and Clark find their route to the Pacific Ocean.  Sacagawea helped Lewis and Clark by arranging an agreement with the Shoshini to borrow horses.  Soon, the Shoshoni were preparing to move because of buffalo herds.  Lewis, Clark, and Sacagawea then asked for more horses and by Augest 29, the shoshoni gave them 29 more horses.  The next route they were going to take was the Columbian River which required moving their boats in addition to thier horses. Going through the Columbian river would help them reach their goal to going to the Pacific Ocean.   The horses pulled the boats for Lewis, Clark, and Sacagawea.  While Sacagawea was passing through the Bitterroot Mountains, it started to snow.  Because of this weather, a lot of their horses passed away.  One of the horses fell and crashed their writing desk.  They then used the broken wood for fire wood which provided them warmth in this terrible weather.  The expedition didlast a long time, but it eventually succeeded.  This journey prabably helped future generations because now days we don't have to travel as far as we would have had to if that expedition did not take place. A coin was made after Sacagawea in 1999 shown on the side.  This coin was made because there was no portraits of her.  She was very limited with herself, so a coin was made instead of a potrait.  This coin was worth $1.00 in U.S money.
