Every spring the great migration resumes, animals of the sea and air swimming and winging their way north. In the recent decades a new species has taken up the route, plowing resolutely north with the hopeful promise of long summer days before retreating south as the waves build, the sun dims, and the rain pelts like daggers. Like the Arctic tern, many will shift their attention to the southern hemisphere, other rushing for the promise of lawn chairs, t-shirts, and mai thais of the Caribbean, following not the food but the money. The cruise ship has become the newest migratory species.

But from May through September they reside in the Pacific Northwest, their roosts in Seattle, Vancouver, and San Francisco, their feeding grounds the towns of Juneau, Ketchikan, and Skagway, sustaining on a diet of generic cotton t-shirts bearing the ports name, postcards, and diamonds mined on the other side of the world. Many pass by quiet Gustavus, its dock offering no hope or promise of future ports, the town’s walls barred against such an invasion of 1500 people into a town of 350. To reach Gustavus is a deliberate act, an independent flight or ferry ride from Juneau. One does not wake up, stagger down the ramp, and ask where their tour is meeting.

For most the true treasure is not in the town, but in the great mythical bay standing just to the west. Where 3.3 million acres of wilderness offers that many set out for. The open box on the bucket list begging to be checked (next year we’ll knock Europe off the list!). An Alaska devoid of t-shirt companies and concrete. This is the Alaska of John Muir and Jack London, wild, and free, an untamed land in an overdomesticated world. But from nine stories up, in a cabin bathed in artificial light, the heater blowing merrily, how tame it can all still feel.

Like an low budget nature documentary the acreage glides past. Mountains, bays, and glaciers in a 13-knot parade. There’s no struggle against the tide or wind, no resigned paddle onward as every promising beach contains another Grizzly landlord. In the bay at 8, Margerie Glacier by noon, Icy Strait by evening. Eight hours, 65 miles, and on to who knows where. Never touching, never tasting, scarfing it all down as quickly as possible. Fast food tourism.

Yet. Whether intentional or not. They’re here. The door to wilderness and the sublime left ajar. The cruise ship the keyhole with thousands elbowing each other out of the way to press their eye against it. To see, even if just for a day a sliver of the Alaska they’ve read about. And in that sliver, lies opportunity. To express that to see Glacier Bay is not the same as living it.

Here lies one of the last places on earth waiting not to be changed but to change. To recreate us like the glaciers did. A reminder that we are never complete. That like a river of ice, constant motion is necessary. That are own natural succession is always in progress. That it’s never to late to surge like like the Grand Pacific Glacier hundreds of years ago, charging south as fast as a running dog. All we have to do is let it.

Many will glance through the keyhole, snap a photo, shrug their shoulders, and move on. But for some, perhaps a cruise is the first step, leaving them in awe, thirsting for more, something authentic. Those eight hours will leave them wanting to meet the bay on its terms, on its level, from the seat of a kayak, at the feet of the glaciers, discovering their inner Muir. If they return it’ll be on their own journey of self discovery, with a can of bear spray in one hand and a tide chart crumpled in the other. And when they return to the bay, it won’t be by accident.
