Nice web cam, yes? I keep it, and another of Puget Sound/HoodCanal and the Olympics on tabs so I can check them out when I need to during the day. Yeah, the bison and the geysers have coexisted there a long time Robert. They walk all around the geysers, though we humans stay on the boardwalks as we cannot sense the thin spots in the earth like they seem to be able to do. Tales of that era from Clark's travels after he and Lewis explored the continent are among the earliest written records of the area. The bison hang out in the Old Faithful geyser basin, which extends quite a ways from the view you are seeing, but are not usually hanging out right in front of Old Faithful next to the board walk from Old Faithful Inn.
David, I would not get so close either. In fact, they advise against it when you are there. We go there every year or so, typically in spring when the bison babies are out, and the crowds are not yet there.
