Specimen Mountain

This mountain rises to about 12,500 feet in the Front Range of northern Colorado, where exposed volcanic rocks and alpine meadows dominate the landscape. The summit area displays clear geological layers and stone formations shaped by ancient volcanic activity.

The mountain was shaped by volcanic eruptions occurring roughly 27 million years ago, leaving behind the distinctive rock formations visible today. It was previously called Geode Mountain and Mountain Smokes before taking its current name.

The peak holds significance for scientific study, with researchers regularly examining the exposed rock layers to understand Colorado's volcanic past. These geological formations serve as outdoor classrooms where scientists and students learn about ancient Earth processes.

The main access is through established trails north of Milner Pass, where visitors should prepare for unpredictable mountain weather. Proper gear and attention to rapid weather changes are essential for a safe hike.

Red-tinted rocks and yellowish ash deposits near Poudre Lake reveal the mountain's volcanic origins in an unusually visible way. These colored layers are rare evidence of the geological transformations that shaped this peak.
