The Hubologist's camp is a location in Nuka-World.
Aside form the Hubologist camp, this locale is also site of the World's Largest Fire Hydrant, standing over 30 feet tall and weighing 250 tons. Before the Great War, when people carried about such trivialities, it was by built artist Thomas Denton III to withstand a tornado; he even claimed "This thing could survive a nuclear apocalypse."
Denton was correct, but the old diner and rest area has since been fortified by Dara Hubbell's expedition into a true fortress, from which they plan to launch expeditions deep into the Galactic Zone, and they couldn't care less about the piece of art.
To the south are the bathrooms and fuel station, and the World's Largest Fire Hydrant is in the west. The fortified diner is in the north and consists of two stories: the ground floor has a cooking stove and a bedroom for the five Hubologists, and the stairway leads to the roof and wooden looking point.
The Hubologist's camp appears only in the Fallout 4 add-on Nuka-World.
