I never tried to jump my bike across a stream but I did pedal my loaded bike across a major stream called the Mississippi river in 1989 at age 28.

I can't post the picture here but it's on this page:

Most Americans know little or nothing about the Snake river. People have heard the name but don't know where it is, or that it's a tributary of the Columbia river. Hell's Canyon is somewhat famous but few people can name the river in Hell's Canyon. The Twin Falls canyon is only well known to people who drive I-84 across southern Idaho. The Grand Tetons area is the scenic highlight of the Snake river but many visitors hardly notice the river.

The Snake is one of our country's finest and most underappreciated rivers. You got some great pictures for this post.

I remember all the hype around Evel Knievel's Snake River jump attempt. I was 16 years old at the time and I was inspired to try my own jump with my bicycle. I launched myself off a mound of dirt to fly across the 10-foot wide creek in my town. Like Evel, my attempt failed, and I can only blame my leg power. If I had a rocket powered bike like he did, I'm sure I would have succeeded.

We love Pendleton as well and own several of their beautiful wool blankets.

I have short legs and like to spin. 155mm is good for me but surely not for everybody. It took a while to get accustomed to starting from a standstill with the shorter cranks, but when cruising the shorter cranks immediately felt better to me. Less peak sprint power, but better average power because of less dead spots in the pedaling circle. I feel like I can apply power for 100% of the circle. If you're more of a slow cadence rider,traditional long cranks are probably better. I'm glad we now have choices.

What prompted you to stay with the 155 cranks? I know they are popular with the recumbent crowd, especially those with bad knees. I rode Jorge's P-38 perhaps a half mile and it had 155 cranks. It felt like I was pedaling tiny little circles. He gave me the pep talk about their advantages, but I was not sold.

I plan to bike the rim trail that passes underneath the jump ramp, and will probably scramble up to the top just for the view.

This looks like an interesting route. I'll be reading.
While you're in Twin Falls, go see the site where Evel Knievel made his Snake River Canyon jump attempt. You can see the dirt ramp from the Perrine bridge (Hwy 93), but it's possible to drive all the way to the actual jump site.

Yes, most Idaho license plates are the familiar design with horizontal red white and blue stripes, and the Famous Potatoes slogan on the bottom.
The state's official nickname The Gem State dates from territorial days, and is mostly a statement of aspiration. Idaho has many mines (especially silver) but is not a major source of precious gems.

Wait a minute! What happened to "famous potatoes"? Do their license plates still say that?

Buddy, it's ironic that the most desolate (fewest services) part of my route is the hundred miles that I share with the TransAmerica bicycle route. I guess it's also the most desolate piece of the TransAmerica route.
The TransAmerica segment is likely to be the only area I see traveling cyclists. I could also encounter a stray cyclist or two in Jackson, Cody, or Red Lodge. Most traveling cyclists seem to go east-west. Not so many go north-south.

Looks like a great plan. I traveled a tiny bit of it on the Transam. I vividly recall Togwotee Pass, and I ate breakfast at the lodge. It should be a great tour, looking forward to following.

This map really is fascinating...... It shows that if a person drops some Mardi Gras beads into the river in Great Falls, Montana, someone in New Orleans could pick them up. The same thing happens if they're dropped into the river in Ashton, NY, a mere 40 miles from Lake Erie.

I have vivid memories of biking Beartooth pass during my 2004 Yellowstone and Grand Tetons tour. I took an unplanned stormy rest day in Red Lodge while it was snowing on Beartooth Pass. The following day was sunny and the snow had melted off the pavement by the time I got to the top, but there was still a bit of snow on the tundra.

I’ll enjoy following this one, Wayne. In July 1995 I set out to bike from Idaho Falls to Billings myself, but with the plan to bike through Yellowstone and over Beartooth Pass. I think my route as far as Jackson must have been identical to yours. I never made it to Billings though because it snowed in Yellowstone and I deemed Beartooth Pass unbikeable and headed east to Cody instead.
