Overview

About This Attraction

Snow-dusted summit rises above evergreen slopes, framing a shallow bowl on the mountainside. That bowl is a glacial cirque carved by ice during the last ice age. The landscape shows how ice and gravity have sculpted alpine terrain over deep time.

Access

Hiking required; some overlook viewpoints accessible via short spur trails

Main Features

Alpine peak, glacial cirque, rugged scree slopes

What You'll See

Rugged granite and pine, alpine meadows; distant rim of the Grand Canyon of the Yellowstone; cirque basin carved by ice

What Makes It Special

Part of the Yellowstone Plateau; high-elevation alpine terrain atop an active volcanic region with glacial imprints and a nearby hydrothermal system

Best Time to Visit

June–August: roads and most trails are open, with sunrise and early-morning light highlighting the geology.

Safety Considerations

Gravity hazards near cliffs; unstable ground at hydrothermal zones; high altitude and cold winds; wildlife; stay on designated trails and follow posted warnings.

Visitor Tips

Look for bedrock exposure and rock flour at the overlook.
Stay on marked trails; the ground around thermal and cliff edges is unstable.
Parking fills by mid-morning in peak season—arrive before 7–8am if you can.
Use sun protection and bring layers for altitude and wind.
