Crammed with tourists, Alaska's capital wonders what will happen as its magnificent glacier recedes

A record number of cruise passengers are expected this year in Alaska's capital, drawn by wonders such as the long-retreating Mendenhall Glacier

JUNEAU, Alaska — Thousands of tourists spill onto a boardwalk in Alaska’s capital city every day from cruise ships towering over downtown. Vendors hawk shoreside trips and rows of buses stand ready to whisk visitors away, with many headed for the area’s crown jewel: the Mendenhall Glacier.

A craggy expanse of gray, white and blue, the glacier gets swarmed by sightseeing helicopters and attracts visitors by kayak, canoe and foot. So many come to see the glacier and Juneau’s other wonders that the city’s immediate concern is how to manage them all as a record number are expected this year. Some residents flee to quieter places during the summer, and a deal between the city and cruise industry will limit how many ships arrive next year.

But climate change is melting the Mendenhall Glacier. It is receding so quickly that by 2050, it might no longer be visible from the visitor center it once loomed outside.

That’s prompted another question Juneau is only now starting to contemplate: What happens then?

“We need to be thinking about our glaciers and the ability to view glaciers as they recede,” said Alexandra Pierce, the city’s tourism manager. There also needs to be a focus on reducing environmental impacts, she said. “People come to Alaska to see what they consider to be a pristine environment and it’s our responsibility to preserve that for residents and visitors.”

The glacier pours from rocky terrain between mountains into a lake dotted by stray icebergs. Its face retreated eight football fields between 2007 and 2021, according to estimates from University of Alaska Southeast
