Fish Canyon Tuff

The Fish Canyon Tuff spans across the landscape with volcanic rocks and consolidated ash deposits forming distinct geological patterns in the mountainous terrain.

This volcanic formation emerged from a massive eruption at La Garita Caldera approximately 28 million years ago, releasing 5000 cubic kilometers of material.

Scientific researchers and geology students regularly visit the formation to study volcanic processes and collect rock samples for laboratory analysis.

Visitors can access the formation through designated trails, with spring and fall offering moderate temperatures for geological exploration and outdoor activities.

The formation contains preserved fragments of ancient volcanic glass, minerals, and rock materials that reveal details about past geological conditions.
