A mixture of land use - perhaps the darker brown/green areas were something like a crop to provide hay, while the light brown/golden fields are soon to be harvested wheat.
The harvest in full swing.
The ubiquitous grain elevator. There's some evidence that a rail line used to follow the route of this road (US-195). But like many such lines, with a limited time use, it has been abandoned and the land returned to grain growing in many areas.
Taken from just off US-195, showing a harvested field across the road. In the background, the hill with the trees has been taken to the next step - the stubble left after harvesting has been ploughed in.
SR-127 near Dusty was being resurfaced. There was a flagger on the road, and when I stopped, he said it would be a few minutes before the lead car returned. So I got off the bike, removed some clothing as the temperature was rising rapidly and took a photo. And there was no shade anywhere nearby.
Crop harvested, and the stubble ploughed into the ground for next year. And not a tree in sight!
After a number of minutes, getting hotter all the time, the truck came through, and we could proceed on our way. But it was a nice new road surface, and a pleasure to ride on. Especially since I was at the head of the queue!
Next stop was Central Ferry, where the road crosses the Snake River.
