Old Reliable Geyser

Old Reliable Geyser is located close to an observation point in the Mount Rushmore National Memorial. It is an allusion to the Old Faithful Geyser located nearly 300 miles to the west in Yellowstone National Park.

Agent P crashed the Drill-inator into the Geyser to redirect its next eruption towards the memorial and cool the lava that forced its way out of the mountain. Details of this event can be seen in Candace Loses Her Head.
