Kinda, sort of purposely a day late.
July 1, 1825 was the date of the first official rendezvous in the Rocky Moutnains.
The Ashley and Henry caravan assembled at the designated spot to trade for furs from the trappers and Natives in the region.
From Ashley's journal:

On the 1st day of july, all the men in my employ or with whom I had any concern in the country,
together with twenty-nine, who had recently withdrawn from the Hudson Bay company, making
in all 120 men, were assembled in two camps near each other about 20 miles distant from the
place appointed by me as a general rendezvous, when it appeared that we had been scattered over
the territory west of the mountains in small detachments from the 38th to the 44th degree of latitude,
and the only injury we had sustained by Indian depredations was the stealing of 17 horses
by the Crows on the night of the 2nd april, as before mentioned, and the loss of one man killed on
the headwaters of the Rio Colorado, by a party of Indians unknown.
On the 2nd day of july, I set out on my way homewards with 50 men, 25 of whom were to accompany
me to a navigable point of the Big Horn river, thence to return with the horses employed in
the transportation of the furs. I had forty-five packs of beaver cached a few miles east of our direct
route. I took with me 20 men, passed by the place, raised the cache, and proceeded in a direction
to join the other party,

Yep, hence the unplanned, yet significant one day delay.

I'll be raising a toast to those men this evening.

A group of tough men that helped to settle our west.

Wish I could travel back in time and participate. Thanks for the timely report K.
