Rugged, wild, and incredibly scenic. Gorgeous alpine lakes, dancing Northern Lights, abundant wildlife, meadows brimming with wildflowers, and mighty glaciers all find their place in Montana’s Glacier National Park.
But what will we call it when the glaciers are gone?
NASA’s latest report has some grim news: By 2030, Glacier National Park will no longer have any glaciers. The shrinking of the ice is real, and it’s happening fast.
Don't Focus on the Date

When President Taft created Glacier National Park in 1930, it was home to around 150 glaciers. Since then, the number has dropped to fewer than 30. "Things that happen in geologic time are happening during the span of a human lifetime," Dr. Daniel Fagre, a research ecologist for the Northern Rocky Mountain Science Center, told National Geographic. "It's like watching the Statue of Liberty Melt."
"People focus too much on the date," Dr. Fagre tells NASA. "But the basic story is still true. These glaciers will be more or less gone in the next several decades."
A TOUGH TIME FOR WILDLIFE

At Clements Mountain, with a summit around 8,800 feet above sea level, what used to be a glacier has now become a shrinking snowfield. “This snowfield will vanish,” said Fagre in an interview with New York Times. “When that happens, this whole area will dry up a lot. A lot of these alpine gardens, so to speak, are sustained entirely by waterfalls and streams like this. And once this goes, then some of those plants will disappear.”

Dr. Fagre said that the implications are “almost too great to count” for wildlife.
Tree lines may creep up mountains, and the meadows where mountain goats keep watch for mountain lions will be gone. Hummingbirds that depend on glacial lilies for nectar may arrive in spring, only to find that the lilies have already blossomed and there is no food. With less snowfall and glacial runoff, streams may dry up, and cold-water fish and insects may become sparse.
RIGHT BEFORE OUR EYES

The Blackfoot-Jackson basin contains the largest glaciers in the park. This animation shows the shockingly quick retreat of the glaciers from 1984-2015. The blue color represents “permanent” snow and ice, and the red a burn scar from the Thompson forest fire.
As the global and regional climates continue to warm, the frequency of fires in the park is expected to increase. The clearest indication of climate change is melting ice and glaciers
Approaching 2030, the glaciers will become “small insignificant lumps of ice on the landscape,” Fagre said. “These tiny remnants could last 10 to 15 years past that time if they are in sheltered places, but the park will no longer really have viable glaciers.”
If you want to see Glacier's glaciers, you'll have to visit soon.
Even the most experienced riders aren't immune to unstable snowpack. Maurice Kervin learned this firsthand last Friday while snowboarding on Loveland Pass, his 65th day of riding this season. Kervin and his ski partners had been keeping a close eye on the avalanche forecast all week. Although the danger had actually dropped, Kervin recalls feeling unsure of the conditions. Intending to ski a line called 'No Name,' the pair set out, and tested snow stability along the way, not finding any red
As skiers we're always talking about the snowpack and how stable or unstable it is, but what does that really mean? This slide in Hyalite, Montana is a pretty good example of 'unstable snowpack.' Triggered by a skier who made it all the way down before the face actually broke (one lucky fellow), the slide was a pretty classic slab avalanche. Our friends at the Gallatin National Forest Avalanche center broke down what happened with slide. Essentially, it was a slab of wind packed snow
Big waves are nothing new to surfers these days, but how about to skiers? California skier Chuck Patterson decided to combine two of his favorite things-- big wave surfing and skiing on some of Half Moon Bay's biggest swells. Using custom skis designed specifically for this feat, and taking inspiration from Patterson's late friend, Shane McConkey, they allow him to carve the waves as he would snow. Fitted with classic ski bindings, and worn with regular ski boots, the carnage if Patterson
