On our first full day in Yellowstone National Park, we hiked a piece of the North Rim Trail. The part of the trail we hiked is a short and sweet 2.8 miles, including the walks down to the brink of both the Upper Falls and the Lower Falls of the Yellowstone River. What I found interesting is that the park provided convenient parking for each waterfall, which caused almost everyone to drive and park in one of those lots, and hike just the bit that took them down to one of the waterfalls. We were the exception and saw no one else hiking the bits in between the waterfalls.
At one point while we were hiking back to where we had parked our car, we found ourselves in the midst of a group of Clark's Nutcrackers. These birds are in the same family as crows, and this group of five or six was making lots of noise. At first I thought that there might be a hawk, or owl or some other animal that they were mobbing, but I never saw anything to support that theory. So, it may have just been a rowdy group, or maybe we were the ones getting mobbed.
