Runner Notes

The first section from the trailhead is steep, but the rest is a pleasant grade. The trail is busy with people. Grizzlies and moose are common visitors to the trail, so be alert.


This popular trail breaks off of the Ptarmigan Trail and continues through trees with intermittent views that gradually break out to incredible views of the serrated, knife-edge ridgeline of the Ptarmigan Wall. Flowers bloom late into the summer with the notable beargrass being particularly stunning. Iceberg Creek creates a waterfall visible from across the valley.

You work your way along the Ptarmigan Wall towards the towering walls of the cirque. As you get closer, you enter into flower-covered meadows and a little pocket lake that makes you think you may be there. You continue along the trail and go over a little rise and the lake comes into view. Icebergs float in the lake throughout most summers. The vertical walls rise dramatically from the lake's opposite shores.

Brave souls jump into the water and swim to icebergs for bragging rights.

Flora & Fauna

Beargrass, fleabane, and many other flowers grace the forest and meadows. Mountain goats can be seen in the cliffs while bears and bighorn sheep frequent the meadows. Moose are often visible as they feed in the willows below.
