Freshmen at the Colorado School of Mines are expected, but not required, to participate in the M-Climb. During this climb, students carry a ten-pound rock up Mt. Zion. At the top of the mountain, they are then told to whitewash the M. While also being a mild hazing tradition, students take great pride in this process as it symbolizes the struggle they endure at the school to reach their goals. At graduation time, seniors are invited to return to the M and retrieve a rock to keep. This symbolizes the students taking the knowledge and skills they've learned with them into the next stage of their lives.
