The fort has stood the test of time, maintaining its position as Yellowstone National Park's central management facility from its founding site—a lasting tribute to the importance of its earliest functions.

Accessibility and Current State

Structures like officer housing, barracks, and administrative offices offer glimpses into daily life when the U.S. Army managed Yellowstone.

Interpretive displays provide context about the fort's role and transition to National Park Service leadership. While road traffic into Mammoth can build in summer, the 1.5-mile roundtrip trail is accessible for various abilities.
