Mount Zion, Summit in Golden, Colorado, US.

Mount Zion is a summit located in Golden, Colorado within Windy Saddle Park, rising to about 7,062 feet. The peak offers views of Clear Creek Canyon and the surrounding Denver region.

The Colorado School of Mines established the large white 'M' on the mountain's eastern face in 1908, making it one of the earliest mountain monograms in the US. Since then, this symbol has become a permanent part of the school's identity and the landscape.

Every year, new students at the Colorado School of Mines maintain a tradition by climbing the mountain to add a rock to the illuminated 'M' display. This habit connects visitors with the school's history and creates a personal bond with the place.

The summit can be reached via a short hiking trail from the Windy Saddle parking area, though signage is minimal and attention is needed along the path. Visitors should be prepared for uneven terrain and varying conditions depending on the season.

The white "M" on the mountain has been permanently lit since 1932. Freshmen at the Colorado School of Mines each carry a rock up to add to the letter, and may take one with them when they graduate, a practice dating to 1908.
