A jagged granite point rises above a rugged alpine basin, visible from distant views along the Going-to-the-Sun Road. The pyramid silhouette anchors the skyline as Glenns Lake reflects the early-morning light. This peak is a textbook glacial horn, carved by ice that devoured the surrounding valleys as glaciers receded. The bedrock here is ancient Belt Supergroup granite, born on the sea floor hundreds of millions of years ago.
Late June through September; early morning light over Glenns Lake is ideal; roads are typically clear, midday glare is harsh.

Yes. Parking fills very early in peak season. Plan an extremely early start or look for biking-based options from a base area.
No. The final ascent is a scrambling, trail-less route with exposed edges; use bear spray, sturdy footwear, and travel with experienced companions.
If you crave alpine granite and a classic horn silhouette, the payoff is substantial, but be prepared for a long, demanding day.
Not recommended. The terrain is steep and exposed; maintain close supervision and avoid the summit routes.
Distant viewpoints along Going-to-the-Sun Road offer angle of the peak, but the actual summit requires scrambling and is not a drive-up viewpoint.
