We were in bed before the sun last night. Today is Christal day for exploring water falls. I hoping to see a moose on our travels, we've seen enough buffalo grazing and lying around. We got to touch the Yellowstone River and it's closed to fishing for the trout run. We were only going as far as the Petrified Tree but wound up in Mammoth Springs, wow, what a busy place! Saw the upper and lower falls and tower falls, which wasn't as grand as put out to be. Near Fishing Bridge, we witnessed a buffalo swim across the Yellowstone River. Didn't know they could swim.
