Welcome to the boards SSS, great pics, great cattle, great scenery. We had a cow much like your old Snake there. We called ours Spookum, and plenty of coyotes and local mutts knew her well. Didn't need a dog or a donkey if she was in the calving pasture.
Obviously you'ev got a program going there. Anyone who talks about building organic matter knows that soil is the #1 priority, good for you.
