Old Faithful is primarily composed of volcanic rock and minerals, characteristic of the geothermal features found in Yellowstone National Park. The geyser itself is formed from a combination of underground reservoirs filled with superheated water and steam, which are connected by fissures and fractures in the rock. The unique geology of the area, including a large caldera from past volcanic activity, contributes to its eruptions and structure.
