A lone beast welcomed us as we arrived at Yellowstone Lake.
Hundreds of bison were placidly grazing in a grass basin.
Ahem, why did they give us this warning notice....
...because a stampede is possible. May the best man win.
Oh, no! Now he is after us...
Time for a gathering where the iron horses go.
And for some divine reassurance.
We saw mud pools, geysers and pink and white terraces, too.
