Trip Report Specimen Ridge - Yellowstone NP

I hiked along the Specimen Ridge trail on September 19. Almost as soon as I was on the trail I saw a coyote "mousing" and a pronghorn buck. After I got up on the ridge proper, I saw 2 bull bison coming down the trail. I moved off the trail but apparently not far enough, they followed me for a bit as I continued to move up the ridge off trail. The weather was very nice after the cold wind and snow earlier in the week, sunny and with a light breeze. At the junction with the Yellowstone Picnic trail I looked over into the Yellowstone River canyon. I hiked up until I was tired and then cut off trail to the Agate Creek trail hoping to look over into the Yellowstone canyon. I wasn't able to see down into the canyon without going further than I wanted, so I hiked out back along the Agate Creek trail. I saw several elk antlers, skulls and bones of pronghorn, bison, and elk, and another pronghorn buck. I made it out about 3pm without having met another hiker on the trail. A couple were at the parking area just about to start up the trail.
