Spent the whole day exploring Yellowstone. We saw Old Faithful erupt twice while we were there (really fortunate because it happens every 90 minutes or so). We walked around many pathways to see other geysers and "pools" of boiling water. Really an incredible sight and amazing to think that magma 5 miles below the surface is causing it. We posed for a picture at the Old Faithful sign (a repeat of us from about 10 years ago when we last visited Yellowstone). As we looped around and headed south again it was just the right time to see the Bison moving toward the river. Wow, the first one was strolling down the side of the road and then many dozens more were either at the waters edge, swimming across the river, or lounging in the meadows as we drove further south. They are incredible. To top it off we saw some elk in the meadows as we drove back to Jackson.
