It is possible to see several tourists, who will be taking pictures. The geyser is surrounded by a small fence so that people do not get too close.
The name "regular" is probably referencing to its jet of superheated water, which can be seen every 30 seconds, lasting for about five seconds. Although seemingly powerful, the jet blast is incapable of physically affecting the player or others. This is the only geyser in the entire state.
This is one of many locations within the game that serve no storyline purpose, but exists to provide additional color and detail to the game world, although the player can pass by during Interdiction.
