I had hiked around 13 miles the on Tuesday and was getting a little fatigued with the hiking and lack of sleep. This combined with not setting the alarm clock properly, and I woke up on Wednesday late, at around 5:30am. I had planned on hitting the large drainage, but didn't have time to get there so I decided to get back up on the mountain. At least I might run into some grouse. By the time I got to the trail, I could see to walk without a flashlight, so I eased my way up as quietly as I could, with the wind in my face. I was looking, but apparently not well enough. A little more than half way up, I spooked a 4x4. I was less than 10 yards from him, but couldn't see him because he was behind a small pine tree on my left and as I started to step clear of it he saw me. He ran out to 35-40 and stopped quartering away, but there was brush behind him and me. In hindsight, I believe that I could have knelt down and had a shot, but I thought that he was probably unsure of what he was running from, so I waited a few seconds and when he took a couple more steps into cover, I eased back behind the pine and gave a couple of cow calls. No response, and he continued away through the clearing that he was in. Exciting, but I obviously wasn't alert enough. Live and learn. I continued to hunt the mountain the rest of the day, but the only fresh sign that I saw were the tracks from that bull. I wonder if he was just wandering through, looking for love? Saw a bunch of grouse, but didn't take any shots since I was really after elk. I went back to camp, took a quick lunch, and made plans for the afternoon. I had now spooked 2 elk in that same small drainage, possibly the same elk, but I decided to sit further up the drainage in the evening, into the night, in case elk were making their way to the creek for a drink, and if I didn't see anything, I brought a blanket and planned on sitting into the night to listen for bugling or cow calls, trying to pin them down. I wound up not seeing anything during daylight, and sat until 3am without hearing any elk activity. At that point I packed up my gear and headed down the mountain, planning on going to the crest of the drainage before daybreak again.
