The hike to Iceberg Lake along the open ridge of Mount Henkel offers incredible views the entire way. Mount Wilbur is to the left, with the 9,145-foot Iceberg Peak rising behind. Glacier NP has 54 mountain peaks above the 9,000-foot level.

Prime Grizzly Habitat

The Iceberg Lake Trail crosses through prime grizzly habitat. We were lucky to see two grizzlies on our first day of hiking.

Iceberg Lake

Iceberg Lake is a beautiful aquamarine tarn surrounded on three sides by 3,000-foot cliffs. A tarn is a mountain lake that fills a bowl carved by a glacier. Icebergs dominate Iceberg Lake through July but were absent on this warm September day.

Surrounded by Giants

Red Rock

The mountains in the Many Glacier region are striped with a layer of red rock called argillite. Argillite is a sedimentary rock formed by the compression of multiple layers of iron-rich mud. This area was once a shallow sea, and this layer of iron hematite turned bright red.

Burst of Colors

Adding to the fall colors of the hillside vegetation are the layers in the mountains behind. These mountains started as sediments deposited in an ancient seabed and slowly hardened into thick layers of limestone, mudstone and sandstone. About 60 million years ago, a massive 300-mile long slab moved more than 50 miles west-to-east, thrusting up to create the Lewis and Clark Mountain Range you see here that runs through the heart of Glacier National Park.
