As I was approaching the saddle just south of the Coyote Mountain summit, I started hearing a loud thud sound. There were only two things I could think of that would make that sound: either a rockfall or bighorn sheep. Sure enough as I came over the hill I saw this herd of 9 in a grassy area staring at me. I never actually saw them ramming their horns together, but only heard them. They soon took off running.
