Pogo Agie River and Mountain Men

We finally left Denver on Nov 2nd and traveled to Riverton Wyoming. We had a very nice visit with Joe’s mother, Dorothy; Sister Mary and brother-in-law Mel. We also dusted off our GPS units and went searching for GEO Caches and of course treasures that we could not live without. We left Riverton on Monday Nov 8th and traveled west too Lander, crossed the Pogo Agie River and over South Pass. South Pass is near where the Oregon Trail crossed the Continental Divide. The Pogo Agie River, Riverton, and Lander areas have history dating back to the mountain man era.

1829 Rendezvous – Lander, Wyoming

1829 rendezvous on the Popo Agie (Popoasia, Little Wind River) north of Lander, Wyoming was the first rendezvous held east of the Continental Divide. There was a small gathering of mountain men on the Popo Agie, and as soon as the trading was concluded, Sublette left for Pierre's Hole in Idaho with the remaining trade goods. Sublette traveled over Togwotee Pass into Jackson Hole and then over Teton Pass into Pierre's Hole. There he found Jedediah Smith, who had been in the Oregon Country for two years, and David Jackson. Robert Newell recorded that at this second rendezvous there was one hundred and seventy-five mountain men.

1830 & 1838 Rendezvous – Riverton, Wyoming

The 1830 supply caravan, led by William Sublette, consisted of eighty-one men on mules, ten wagons drawn by five mules each, two Deerborn carriages, twelve head of cattle, and a milk cow. Sublette left St. Louis on April 10th and arrived in the Wind River Basin on July 16th. The supply caravan averaged fifteen- to twenty-five miles a day. Sublette stopped for a rest on July 4th, 1830 at a large rock outcropping on the Sweetwater River. The rock is called Independence Rock.
The Smith, Jackson and Sublette firm collected one hundred and seventy packs of furs with a value of eighty-four thousand four hundred and ninety-nine dollars. This was the firm's most profitable year, but the partners had concerns over the future viability of the fur trade. At the Riverton rendezvous of 1830, Smith, Jackson, and Sublette sold out to a partnership of Thomas Fitzpatrick, James Bridger, Milton Sublette, Henry Fraeb, and Jean Gervias, but William Sublette remained the St. Louis supplier for the rendezvous.
Fitzpatrick, Bridger, Sublette, Fraeb, and Gervias named the new company the Rocky Mountain Fur Company. Although the term Rocky Mountain Fur Company is widely used in fur trade history, the period from 1830 to 1834 is the only time that there was an actual company called the Rocky Mountain Fur Company.

Closing note:
We know a mountain man named “Three Rivers” he can mix clear water from the Pogo Agie River, and two other rivers in order to get a orange colored liquid.
