Hubert, Well, at least the first Letter of Wisconsin is in the name of the State wjere Old Faithfull is located. It's Wyoming close to the Montana Border or in other words, it's inside Yellowstone National Park.
Just look for the place on the U.S Map, where the States Montana,Idaho and Wyoming meet (ID,MT,WY). Exactly there is Yellowstone National Park, thus Old Faithfull is also there. Actually, if you look at this spot on the small Panoramio map on the right side of this page, you'll see a small green spot - that's Yellowstone.
