Years: 1824 - 1824
Stiff native resistance forces Ashley and Henry to abandon the posts they have established.
Henry retires from the late Manuel Lisa's company in 1824 and returns once more to lead mining.
Ashley devises the revolutionary rendezvous system, in which company agents are to meet independent trappers annually in a predetermined location at the end of spring to exchange trade goods for beaver pelts.
The first rendezvous is held in 1824.
