Top O' and I were still hiking together when we reached Two Ocean Pass at 2:30 p.m. This junction was where we turned to leave the CDT and follow the Big Sky/Super Butte Alternate.
For a moment, I regretted we were turning here. If we continued another eight-tenths of a mile on the CDT, we would come to one of the most unusual spots on the trail, if not the world. Two Ocean Creek flows down from a ridge until it reaches that point and forks in two directions.
If you were to turn left from there to follow the creek's flow downstream, you would eventually reach the Yellowstone River, which flows into the Missouri River. That river would eventually take you to the Mississippi River. After traveling more than 5,800 miles, you would reach the Gulf of Mexico and ultimately the Atlantic Ocean.
If you chose to turn right at the fork instead, you'd eventually get to the Snake River. Following that would take you to the Columbia River, which empties into the Pacific Ocean.
The spot just ahead on the CDT is called the Parting of the Waters and is recognized as a National Natural Landmark. It's not a unique land feature, however. A creek in Canada has a similar split, with one side flowing to Hudson Bay and the Atlantic and the other flowing to the Pacific.
