Indeed they feared no molestation.

No Indian band would think of attacking a fortress which a thousand warriors had declared impregnable.
As soon as the returning spring would permit, the trappers broke up their encampment on the Yellowstone, and passing directly west through the very heart of the Blackfeet country, planted their traps on the head waters of the Missouri river.

For three months they traversed many of the tributaries of this most majestic of streams.

They were moderately successful, and in the early summer turned their steps south, crossing the mountains to dispose of their furs at the Rendezvous, which was again held on Green river.
