One night Captain Clark counted as many as 17 thorns that he pulled from his feet.
Seaman, Captain Lewis's dog, also suffered.
Even though they traveled by canoe, they had to walk to keep the canoes light. And often, the water wasn't deep enough and they had to pull the canoes over sandbars and islands. All they wore on their feet were moccasins.
Can you imagine how brave these people were?
And what is even more amazing?
They never complained.
