Glacier Bay National Park and Preserve
Glacier Bay National Park and Preserve Review
Near the northern end of the Inside Passage, Glacier Bay National Park and Preserve is one of America's most magnificent national parks. Visiting Glacier Bay is like stepping back into the Little Ice Age—it's one of the few places in the world where you can approach such a variety of massive tidewater glaciers. Sounding like cannon fire, bergs the size of 10-story office buildings come crashing from the "snout" of a glacier, each cannon blast signifying another step in the glacier's steady retreat. The calving iceberg sends tons of water and spray skyward, propelling mini–tidal waves outward from the point of impact. Johns Hopkins Glacier calves so often and with such volume that large cruise ships can seldom come within 2 miles of its face.
Glacier Bay is a still-forming body of water fed by the runoff of the ice fields, glaciers, and mountains that surround it. In the mid-18th century, ice floes so covered the bay that Captain James Cook and then Captain George Vancouver sailed by and didn't even know it. At the time of Vancouver's sailing in 1794, the bay was still hidden behind and beneath a vast glacial wall of ice, which was more than 20 miles across and in places more than 4,000 feet in depth. It extended more than 100 miles north to its origins in the St. Elias Mountain Range, the world's tallest coastal mountains. Since then, the face of the glacial ice has melted and retreated with amazing speed, exposing 65 miles of fjords, islands, and inlets.
In 1879, about a century after Vancouver's sail-by, one of the earliest white visitors to what is now Glacier Bay National Park and Preserve came calling. The ever-curious naturalist John Muir, who would become one of the region's earliest proponents, was drawn by the flora and fauna that had followed in the wake of glacial withdrawals; he was also fascinated by the vast ice rivers that descended from the mountains to tidewater. Today the naturalist's namesake glacier, like others in the park, continues to retreat dramatically: the Muir Glacier's terminus is now scores of miles farther up the bay from the small cabin he built at its face during his time there.
Glacier Bay is a marvelous laboratory for naturalists of all persuasions. Glaciologists, of course, can have a field day. Animal lovers can hope to see the rare glacial "blue" bears of the area, a variation of the black bear, which is here along with the brown bear; whales feasting on krill; mountain goats in late spring and early summer; and seals on floating icebergs. Birders can look for the more than 200 species that have already been spotted in the park, and if you're lucky, you may witness bald eagles engaging in aerobatics.
A remarkable panorama of plants unfolds from the head of the bay, which is just emerging from the ice, to the mouth, which has been ice-free for more than 200 years. In between, the primitive plants—algae, lichens, and mosses—that are the first to take hold of the bare, wet ground give way to more-complex species: flowering plants such as the magenta dwarf fireweed and the creamy dryas, which in turn merge with willows, alders, and cottonwood. As the living plants mature and die, they enrich the soil and prepare it for new species to follow. The climax of the plant community is the lush spruce-and-hemlock rain forest, rich in life and blanketing the land around Bartlett Cove.
