Every 90 minutes (give or take), this geyser reminds us why it's called Old Faithful. Old Faithful earned its name in 1870 during the Washburn-Langford-Doane Expedition because members of the expedition noticed that it erupts at regular, predictable intervals. Curious about the geologic forces behind Old Faithful's eruptions? Check out the exhibit at the Old Faithful Visitor Center to learn more! #VisitGardinerMT #yellowstonenps #yellowstone #KnowBeforeYouGo #OldFaithful | Visit Gardiner Montana
