The day was sunny and dry, with temperatures starting out in the low 60’s with highs in the 70’s. Winds were occasionally gusty but generally mild.
Day’s distance: 335 miles
Total trip distance: 11,972 miles
It was another 10am start by the time I was out of the motel and done with my Starbucks latte. Initially, I would cross the Snake River Plateau.

There were quite a few energy labs behind guarded gates located along Hwy 20. It reminded me of when I was in the Navy at Nuclear Power School. At the time, there were two prototype training sites – Idaho National Labs and upstate New York. When I stopped at a rest area, the sign below confirmed the prototype training center was in this area.

When I reached Arco, to my surprise I saw a roadside exhibit about the nuclear power development that took place in the area. The sail of the submarine USS Hawkbill (the ‘Devil Boat’ because of its designation USS 666).
The museum curator has been involved in the Navy’s Nuclear Power Program since graduating college in 1957 (if I remember correctly).
Arco was the first town powered by atomic energy on July 17, 1955, a byproduct of the research being performed and makes for good press within the community, I’m sure.
The history of this area had an unexpected connection to my past, despite never having been here, that made me very happy. It’s a small world 🙂
My next quick stop was Craters of the Moon National Monument. This is a volcanic fissure that was active about 2,000 years ago.
There was a short loop to drive around and optionally stop and walk up the pathways.


The rest of today’s riding was about exploring the roads inside the Sawtooth Mountain Range. According to my Butler Motorcycle Map, these would be scenic and fun. They did not disappoint, either. The elevation changes, sweepers and non-technical turns, and steep dropoffs sometimes without guardrails were worth the travel.
The road surfaces were generally in very good shape with some exceptions, where winter damage was evident but either repaired or not too rough.
I kept running into three guys on motorcycles throughout the day. We first passed while they were at Craters of the Moon, then in Stanley, then on the mountains west of Stanley, where we finally talked about our trips.

As it was starting to get late, I focused on getting off the mountain and to my motel in Boise. I’ll likely camp tomorrow night so this may be the last motel stop for the trip. 🙂
Tomorrow I’m hoping to stay at the Hell’s Canyon State Park in Lewiston. I stayed there last summer during my 2014 Trip to Glacier.
I’ve had to do a lot of catching up on your trip posts this morning. This last week has been hectic, to say the least. My dad’s (Paul) mom got sick weekend before last with Pneumonia and had to be hospitalized. With that and her COPD, she passed away last Tuesday. He’s been following your journies too, when he can.
Sorry for your loss, Dennis. I thoughts go out to you and your parents.
