The second day included seeing nine wolves meeting at what was referred to as “the rendezvous” – the meeting place. Later on, we saw four wolves surround a lone bison. The wolves circled the bison for about an hour before they gave up and walked away.

Their departure was encouraged by two other lone bison that had walked from a considerable distance to provide support for the one picked out by the wolves. Biologists thought we might actually witness a bison kill that morning.

(Photo note: Hot water exits thermal areas to ultimately join rivers. As the water moves away from the vent, it cools. Over the years, algae has adapted to living in various water temperatures. As the temperature changes, the algae that can survive there changes. Different algae are different colors. So, as one looks across water moving away from a hot spring, the algae can tell visitors the relative temperature of the water.)
