Union Pass

Joe and I came upon this historical marker on our way home from Jackson. Due to time, we didn't get the chance to "explore" this area, but will be back next year to check it out.
Jim Bridger knew this pass as the “Triple Divide” — a point forming headwaters of three different continental drainage basins. One stream eventually feeds into the Green River, which in turn drains into the Colorado, and finally the Pacific Ocean in Southern California. Another feeds the Snake River, adding to the Columbia which heads for the Northwestern Pacific. The third stream drains into the Wind River, which feeds the Missouri, then the Mississippi, and ends up in the Gulf of Mexico. Captain William F. Reynolds, of the Army
Corps of Engineers, named the pass for the Union Army. He thought it was the center of the
continent. Reynolds was on an 1860 mission for the War Department to find an immigration
route from Fort Laramie to the source of the Yellowstone River.
