How would curves in the river have affected Lewis and Clark journey?

Curves in the river would have significantly impacted Lewis and Clark's journey by altering their navigation and travel time. Sharp bends could slow their progress, requiring them to maneuver their boats carefully and potentially leading to longer travel distances. Additionally, curves might have influenced the availability of suitable landing spots for rest and resupply, complicating their expedition logistics. Overall, the river's winding nature would have presented both challenges and opportunities for exploration along their route.
