This young one and I had an encounter on a predawn hike in the Grand Canyon. I do not know who noticed who first, but I suspect it spied me. It was about 30 yards down the cliff wall from me on a rocky edge to the canyon. I think that both of us were glad the other was not a mountain lion. I was unaware that mountian lions were in this park until I saw a sign on the way to take my pre-dawn hike seeking to get some nice sunrise pics. We spent about 15 minutes checking each other out while I took pics of it.
