This was pretty cool and easy to use. You just need to go to the NPS site and click on Yellowstone and then Webcams. You’ll find a few video tours and the Old Faithful webcam. I was fortunate to see a wolf and Old Faithful erupt within 5 or 10 minutes. It erupts about every 90 minutes, but you will not know when it has last erupted when you click on the link. There is a tutorial about the Geyser area that plays as you watch. The picture is a little fuzzy at times, my husband says they need to take the auto focus off and clean the lens, but all-in-all, it was pretty cool as I’ve said.
