Missouri Breaks - Missouri River
The unofficially named " Sacajawea Rock," top left, appears on the south bank of the Missouri River. It's about 20 minutes up river from Slaughter River - timed while leisurely floating down stream. More bizarre sandstone formations appeared on both sides as the Corps moved steadily up the Missouri. The crew would have observed these geologic formations on May 30th. No journal mentions Sacajawea Rock, but Captain Lewis noted that the air was much drier. So much drier that his ink dried out and his sextant case shrunk and joints came apart.
