I’ve driven Blacktail Plateau Drive, a one-way gravel road on the way between Mammoth Hot Springs and Tower-Roosevelt, a number of times on my visits to Yellowstone. The first time was one of the best, when I came across a couple of cubs high in the trees who slid down when their mother called them. This morning wasn’t too bad either, as a lone male pronghorn was resting in the grass in the early morning. The gate at the entrance has usually been locked at sunrise when I’ve been there that early, which is unfortunate, as there is no way to know without driving all the way out there.
