Where those pictures are taken is a old yard site and alot of the grass is Crested wheat. It is a great spring grass but by mid summer it is quite hard and wolfy. Our native prairie is much better late season grass and the cows could winter on it if the snow didn't get to deep.
In the first pic you can see the fenders on the back end of a old John deere tractor.
I can certainly relate to the genetics you are using. We have used both Sitz Alliance 6595 and TC Advantage heavily in our own herd. A TC Advantage son was high selller in our bull sale this spring. We will be selling Alliance daughters and many heifers bred to Advantage in the Grasslands sale in Swift Current in December. Would be nice if you could make it over, we'd love to show our cattle and some hospitality!
