About This Book

This natural history of the mountain wilderness called Glacier National Park is not a guidebook, but provides an overview of the ecology of the region. At the same time, it is a personal statement, revealing one individual’s response to this rugged, delicate land.

For their consistent cooperation and helpfulness, I wish especially to thank Chief Naturalist Ed Rothfuss and his capable staff. Technical and field assistance came from many; for special thanks, I would like to single out Art Sedlack, Francis Singer, Bert Gildart, Walt Martin, Craig Kuchel, and Danny On. The manuscript profited greatly from the criticism of Douglas Chadwick, to whom I am deeply grateful.

—G.B.

Song of the High Peaks

April again and the wind turns on the Great Plains. Wedges of geese, high and determined, began this storm of spring, their voices sharp as the morning frost. Sicklebills cry to claim the land, sandhill cranes wheel and talk overhead, and everywhere the killdeer shout. Pasqueflowers push the bleak soil aside, beginning the westward rush that I must join, seeking again the sight of mountains.

In Glacier National Park the land is folded up. On the east, Chief Mountain, Curly Bear, and Rising Wolf break the prairie’s hold. When the early French fur trappers saw these peaks glistening in the distance with summer-long snows and perpetual ice, they named this region “the land of shining mountains.” But for all the ice and snow that reflect the summer sun, the park’s present glaciers are but snowflakes compared to the mighty rivers of ice that carved this land. Glaciation, the magnificent sculptor, left its bold signature everywhere, and this park honors with its name the force that shaped it.

But the essential excitement of this land is more than cliff face, spire, and sudden storm. It comes to you when you realize that here is an aggregation of dramatically differing life zones, where a day’s walk can easily take you from prairie and forest to treelimit and tundra; where a dense forest of redcedar and hemlock, similar to the rain forests of the Pacific coast, exists a score of kilometers from the great prairie sea.

Or it comes when you discover that these mountains—young and sharp with shadows, snow-jeweled and newly gowned with forests—are chiseled from the oldest unaltered sedimentary rocks on earth.

I come from the prairie and love its broad strokes; I’ve learned to hear the singing in the grass and to see those long, slow seasons soar the level horizons like gliding hawks. But here I learned to match my days against a wild earth, and in me grew the mysterious need to know a mountain from its every side. Mountains that wear the dawn like yellow hats, repeated in the named and nameless lakes. Mountains that stretch the storms between them and balance rainbows ridge to ridge.

I must see again the secret forest places, where the paleflowered wood-nymphs hover like a breath, and know once more the endless meadows painted camas blue.

I need the perfect freedom of this land, to be able to say, today I will climb Siyeh: to stand, for a time, on the rugged shoulders of this upright earth.

Cycles and Seasons

Bedrock: The First Story

On the trail that connects the Logan Pass visitor center to Hidden Lake overlook there is a shallow pond. Near Hidden Pass, it collects its meltwater from the Continental Divide and sends it down the shallow gorge that drains the Hanging Gardens; as a waterfall it plunges into the upper St. Mary Valley where it becomes Reynolds Creek; joined by other tributaries, it continues its long journey to Hudson Bay.

The surface of this pond is seldom still, for the wind treats it like a sea. Because the water is shallow, the wave action wrinkles the bottom mud into ripple patterns, mimicking the churning waves.

I like to come here early in the morning. Sometimes, arriving before the wind awakes, I catch reflections of the surrounding mountains. Beyond the low bench of Logan Pass the Garden Wall begins, running northward with the Divide. In the eastern valley the pitched peak of Going-to-the-Sun hunkers in the morning light like a tensed warrior. To the south, the incisor Bearhat, beautiful cloud cutter of Hidden Lake Valley, juts above the nearby saddle of the pass. But over this place, standing as fresh monuments to an age of ice, tower the cliffs of Clements and the pyramid Reynolds.
