Answer:
How did Sacagawea contribute to the success of the Corps of Discovery?
She could identify roots, plants and berries that were either edible or medicinal. Sacagawea memories of Shoshone trails led to Clark's characterization of her as his “pilot.” She helped navigate the Corps through a mountain pass—today's Bozeman Pass in Montana—to the Yellowstone River.
How did Sacagawea get involved with the Corps of Discovery?
Lewis and Clark met Charbonneau and quickly hired him to serve as interpreter on their expedition. Even though she was pregnant with her first child, Sacagawea was chosen to accompany them on their mission. Lewis and Clark believed that her knowledge of the Shoshone language would help them later in their journey.
Why was Sacagawea important to the Corp of Discovery?
Recognizing landmarks in her old neighborhood, Sacagawea reassured the explorers that the Shoshone - and their horses - would soon be found. When the Expedition did meet the Shoshone, Sacagawea helped the Corps communicate, translating along with her husband.
