Yankee Jim Canyon - Whitewater and History
Yankee Jim Canyon is a short, narrow canyon on the Yellowstone River about 13 miles north of Yellowstone Park. Yankee Jim Canyon is best known for its whitewater floating as it offers the largest rapids on the Yellowstone River outside of Yellowstone Park (boating on the Yellowstone River is banned in Yellowstone Park). The canyon is less than five miles long and the whitewater rapids are found in the first couple of miles. There are a number of options for access points for a Yankee Jim Canyon float. Rafting and kayaking are popular and there are a number of whitewater rafting companies located nearby.
Yankee Jim Canyon Whitewater Floating
Upstream of Yankee Jim Canyon the Yellowstone River has two very different sections. The 8-mile section that begins at the Yellowstone Park boundary is mostly fast water and whitewater. The river descends quite rapidly and there are a number of class II rapids. At Corwin Springs, MT the character of the river changes significantly as the gradient becomes very gradual and the river gets flat and slow for five miles before entering Yankee Jim. The Canyon is very obvious from the river. As you approach from upstream you are drifting through a broad flat valley while watching the mountains pull together into a deep V shape canyon approaching ahead.
Facing downstream highway US 89 is on your right hand side. Hwy 89 closely follows the Yellowstone River on its journey from Yellowstone Park to Livingston and in Yankee Jim the road is quite close to the river. In fact, there are paved pull outs above several of the rapids. On the left hand side of the river is an abandoned rail bed which once served as the primary means for tourists to access Yellowstone National Park. Today the rail line is long abandoned but in a few places the rail bed is very obvious perched above the river.
The Yellowstone River is undammed and river flows fluctuate significantly on an annual basis. In the early summer the river becomes swollen with snow melt and grows dramatically in size and power. The US Geologic Survey operates a river gauge station at Corwin Springs and has recorded flow information since the1890s. They show that low flows are often below 500 cfs (cubic feet per second) and high flows are often above 30,000 cfs. This is a huge difference and the characteristics of river floating are markedly different at different flow rates. This is especially true in Yankee Jim Canyon and I urge you to make sure you understand the river level and its effect on the rapids when you plan a float. The information here is just a rough guideline and is not intended to be the basis of any decision you may make about floating. You can always check on the flow level at the Corwin Springs Gauge Station
As you enter Yankee Jim Canyon the river?s pace increases and the first rapid comes very quickly. This rapid, most commonly known as ?Yankee Jim?s Revenge?, can be the very difficult because at certain flow levels there is a dangerous wave that's very hard to avoid. The wave itself is quite deceptive and most people who stop and scout from the highway look at the waves and don't consider it to look like any sort of a problem. However, the unique hydraulic of this wave has flipped many a boat. The entrance to the rapid is an obvious V left of center. At high water the wave shows up as a breaking wave about two thirds of the way through the obvious set of waves that are otherwise great fun rollers. Unfortunately, if you're riding the rollers you're likely to hit the bad wave unless you pull hard to escape. It?s possible to enter the rapid in the V and cross above the wave to avoid it. However, at higher flows, especially at flood levels, it is more prudent to stick to the eddies and skate your way down the left-hand shoreline. I always recommend you avoid hitting the wave.
The next rapid you come to in Yankee Jim Canyon is a classic pool and drop rapid called the ?Big Rock? rapid. The rapid is obvious because of the house-sized rock splitting the river in half. At most flows this is the biggest rapid in the canyon and is great fun. As long as you avoid the rock you can bounce your way through the waves but the best run is on the right-hand side of the rock. The first drop into the Big Rock Rapid is a pretty steep drop and as you approach from upstream it almost looks like the river just ends in a flat line. If you are in a multiple boat situation watch the boat in front of you as it briefly vanishes from sight and pops up on top of the first wave below.
Below the big rock rapid is a stretch of fast water and it?s a straight shot down the middle of the river with the Boxcar Rapid approaching just ahead. The Boxcar Rapid is the narrowest point in Yankee Jim Canyon and you can see the sheer rock walls coming together ahead as you approach. Just above the Boxcar Rapid is a stretch of waves that vary in size based on flow. Run them right down the center. The waves rush you towards the choking narrows where the force of the river is piled into a narrow dogleg turn with a big rock in the center of the river. The real danger in Boxcar comes at maximum flood levels. At these super high water levels the hydraulics between those two cliff walls are really significant and it is best to be avoided. Even at ordinary high water this rapid can be a white knuckle experience. From here out the canyon walls pull back from the river and the remaining white-water is of little consequence. However, it's still a beautiful float in a beautiful Canyon. Few people realize that there's excellent fishing for native cutthroat trout on this stretch of the river.
History of Yankee Jim Canyon
Yankee Jim Canyon was named for one of the early settlers to the area - Yankee Jim George. He was a miner who never struck it rich and settled down in the mouth of the canyon. Yankee Jim Canyon was a significant barrier to easy horse and foot traffic and Yankee Jim built a toll road through the canyon. He operated a prosperous business charging people that traveled his road and he added to his business by building a small guest house. Yankee Jim George was a well-known local character full of many quirks. For example, to move stock through on his road he charged a nickel a head for cows but a dime a head for sheep - it was widely known that he hated sheep.
Unfortunately for Yankee Jim, the railroad had plans to make their way through the Yankee Jim Canyon down to the areas around Corwin Springs. The railroad made Yankee Jim an offer for his road but he didn't like that idea one bit and turned them down.
The railroad wasn't going to take no for an answer so they reached into their bag of tricks and sent back east for help. Soon a negotiator arrived with a couple of cases the whiskey. The negotiator visited Yankee Jim and by the time they were done talking the whiskey was gone and Yankee Jim had signed away all rights to his road. The railroad built Yankee Jim a new road that went up and over and twisted around but this was pretty much the end of Yankee Jim's business. The railroad ran along the river and went right by Yankee Jim's house. Every day he'd hear that train and he'd run outside shaking his fist and cursing at the train.
Yankee Jim George was really a well-known storyteller. As a matter of fact, Rudyard Kipling described him as the greatest liar he had ever met. Yankee Jim's tales of fighting bears, wolves and Indians had people amazed at his tales of bravery and daring do. The story goes that in 1902 when Teddy Roosevelt came out to dedicate Yellowstone National Park he heard stories about Yankee Jim and decided he wanted to meet him. The President was staying in his private rail car which was pulled off on a siding at Corwin Springs about 5 miles away. The president sent one of his officers on a horse down to see Yankee Jim messenger brought Yankee Jim the message that the president would very much like to make his acquaintance and would like to have him come visit. Yankee Jim reportedly looked at the messenger and told him ?If Teddy wants to talk he knows where I live.?
Well, of course, this upset that young officer to no end but Yankee Jim refused to change his mind. So the officer had no choice but to ride back to Corwin Springs where he had to face the president. He nervously approached the President and said ?Very respectfully Mr. President, Yankee Jim says you tell Teddy that if he wants to talk he knows where I live.? Legend has it that by the time Roosevelt quit laughing he had saddled up his horse and ridden down to Yankee Jim's cabin where they spent the rest of the day swapping lies. Now this might not all be the truth, but it sure makes a good story
