We have visited Yellowstone 8 or 10 times in the past 50 years, sometimes spending the night in our RV or trailer, and sometimes just spending a few hours, then driving on. Come to think of it, we did spend a night in a hotel in West Yellowstone during one visit — it was in the middle of winter, not the weather we like for traveling in our RV, or in the travel trailer. The pictures were taken any number of years ago, so I’m not sure of the name of this geyser.
============

So many people we have talked to, say they only visited the Old Faithful Geyser when they visit Yellowstone National Park. Well, at the Ranger office at the Visitor’s Center at Old Faithful, they have the locations and the scheduled eruption time for many of the 500 or so geysers that make up a small portion of the 10,000 thermal features in the park.
=============

This is the Great Fountain Geyser — I think — located in the Lower Geyser Basin on the Firehole Lake Drive. Prior to an eruption Great Fountain's pool slowly fills with water and begins overflowing about 40 minutes prior to an eruption.

Maybe, just maybe this is the Great Fountain Geyser, later in the day, or maybe just later in the eruption. This geyser is not easily predictable but has an average interval of around 11 hours.
