Old Faithful is a cone geyser located in Yellowstone National Park in Wyoming, United States. It was named in 1870 during the Washburn-Langford-Doane Expedition and was the first geyser in the park to receive a name. It is a highly predictable geyser and erupts within a 90 minute to two hour period regularly. The geyser and the nearby Old Faithful Inn are part of the Old Faithful Historic District.
Always very crowded with the parking lot filling up fast.
The Old Faithful Inn is one of the grand National Park hotels built at the dawn of the NPS.
The Inn barely escaped the Great Yellowstone Fires of 1988.
