Alaska is known for its incredible glaciers, and Taku Glacier, just southeast of Juneau, is one of the most researched and impressive of them all. Holding records for being the deepest, thickest alpine temperate glacier in the world, it comes in at 4,845 feet thick and extends about 36 miles from its origination in the Juneau Icefield.
Considered a large glacier, even by Alaska’s standards, Taku Glacier is one of the southernmost tidewater glaciers in the northern hemisphere—and the largest of the Juneau Icefield. While other glaciers across the state have been retreating due to warming global temperatures, the Taku Glacier has fascinated researchers by continuing to advance as others have melted away.
Unfortunately, in 2019, it was announced the Taku Glacier was officially in retreat with the rest of Alaska’s glaciers.
As a tidewater glacier, Taku Glacier has advanced over time to block the Taku River then retreated—only to restart its advance again. This is due to its positive mass balance. Snow piles up on the glacier faster than the ice and snow melt, and the grounded terminus of the glacier means it doesn’t lose mass from icebergs calving into the water below.
While all of the other glaciers of Alaska have seen marked recession with climate change, Taku Glacier appeared unaffected—until 2019. NASA photos released that year showed the massive glacier retreating for the first time since studies on it began back in 1946.
The Taku Glacier is more than just one of the most stunning natural sights in Alaska—it’s an essential part of the puzzle for understanding global warming and climate change. Visitors here have the opportunity to stand on the precipice of a global shift, making Taku Glacier as fascinating as it is beautiful.
There’s no road to drive up to Taku Glacier, so visiting this amazing site takes some planning. The Taku Glacier Lodge offers a comfortable place to stay for sightseers, and as a fly-in location, it’s open during the peak summer tourist months of May through September.
Visiting Taku Glacier is an experience you won’t soon forget, and travelers here can spend the day taking a flight over the Juneau Ice Field glaciers and end the evening eating grilled wild Alaskan Salmon at the Taku Glacier Lodge. Whether adventure or incredible scenery is your goal, you’ll find exactly what you’re looking for at Taku Glacier.
