I remember seeing some good fresh tracks on moist soil and residual snow from the night before, which disappeared over what seemed to be a cliff. I had previously never had any luck tracking deer, but I thought this was strange enough that I needed to take a look over the “cliff”. Approaching cautiously, I began to see it was not really a cliff, but it was a very steep little canyon of eroded shale and dirt maybe 200 feet deep, or so, with no vegetation. I could see the tracks angling down into the canyon, with evidence of many slippages. Amused that a deer would even try this, I tried to see how far I could follow the tracks with my binos. I curiously traced the tracks to a buck laying on a little ledge, which was still well above the bottom of the gully below. At first I thought it might have slipped and fell to its death, but it suddenly snapped its head up and starred right at me. I could not have been more surprised, but with a little mental processing I quickly determined he was in easy range of the .270 (I don’t even know if range finders were a thing back then). My first good chance at a muley buck, I nervously got the rifle on him, and sent it. Next thing I know he is tumbling end over end down until it settled on the rim of a nasty gully at the bottom. It was my first shot at a mule deer, so I watched in fear wondering if I would even be able to recover him. After convincing myself that there was probably a way out down through the gullied out canyon, I carefully followed the bucks tracks to the ledge and then slide right down to him on my butt. I was amazed and excited by what had just happened, but also still nervous about getting out. It was obvious that both the deer and I were going to have to drop all the way down into the gully, just to take him apart, and then get out from there.
