So much so that its icy front is no longer holding onto the lake that it created.<\/p>\n
That separation has marked the end of something that started hundreds of years ago.<\/strong><\/p>\n Now, something entirely different is starting to emerge in Alaska.<\/p>\n What is causing the glacier to retreat uphill into the Juneau Icefield?<\/strong><\/p>\n For the past few decades, visitors arriving near Juneau expected the same thing.<\/p>\n The awe-inspiring natural beauty of one of the most iconic states in the US.<\/strong><\/p>\n Towering blue ice spilling into the cold water of the Mendenhall Lake.<\/p>\n That iconic view is now disappearing.<\/strong><\/p>\n With every passing year, the researchers noticed something happening.<\/p>\n The glacier front edge is pulling away<\/strong> more and more.<\/p>\n That natural retreat has accelerated over recent years. Experts measured major thinning across the lower sections of the glacier.<\/p>\n In some parts, it’s lost hundreds of feet of thickness.<\/strong><\/p>\n That change is becoming a profoundly important factor. <\/p>\n The glacier\u2019s lower sections have thinned by hundreds of feet<\/strong> over recent decades.<\/p>\n Alaska’s iconic landscape and features are rapidly changing.<\/a><\/p>\n Experts note that the glacier’s retreat has been taking place since the end of the Little Ice Age.<\/strong><\/p>\n However, climate change played an influential role.<\/p>\n Warming temperatures reversed the expanding process. The glacier began to shrink.<\/strong><\/p>\n Over an exceedingly long time, the glacier carved out the freshwater lake it now sits on.<\/p>\n Ironically, that very lake may now be accelerating the glaciers’ retreat.<\/strong><\/p>\n It can no longer replace ice that has melted away. Due to reduced incoming ice flow in the region.<\/p>\n That remarkable natural imbalance is something we can do little about.<\/strong><\/p>\n Experts estimate that the glacier may reveal new landmasses as it breaks away.<\/p>\n They think the glacier’s surface is melting by up to 49 feet annually.<\/strong><\/p>\n An astonishing rate of retreat for such a huge body of ice. And that is where things get even more interesting.<\/p>\n The separation could reveal new basins<\/strong> and unexplored landmasses in the state of Alaska.<\/a><\/p>\n What is happening has been detailed in a report<\/em><\/a> from the Geophysical Institute of the University of Alaska.<\/p>\n As the glacier melts and breaks away, it may reveal landmasses never seen before.<\/a><\/p>\n Entire landscapes are silently emerging from beneath the ice. But what is going to happen to the glacier?<\/strong><\/p>\n Researchers believe it is now heading back towards the mountains nearby.<\/p>\n For centuries, the glacier held a held on to the lake. That stronghold is coming to an end.<\/strong><\/p>\n Experts note that the glacier is transforming from a lake-calving one into a mountain glacier.<\/p>\n Which explains why the glacier has finally broken away from the lake<\/strong>. After a 400-year wait.<\/p>\n It is heading farther uphill into the Juneau Icefield.<\/p>\n And it could eventually disappear from public view altogether.<\/strong><\/p>\n As it melts, it may lead to flooding in the area. Meaning the landscape itself in Alaska may change, too.<\/p>\n Researchers say reduced ice flow from the Juneau Icefield prevented the glacier from replacing ice lost through melting. <\/strong><\/p>\n Foot by foot, changing its location as it breaks away.<\/p>\n With every part it loses, it is revealing new landmasses and possibly even a few freshwater lakes.<\/strong><\/p>\n Experts warn the retreat could reshape local flooding patterns.<\/p>\n The land that makes this part of the world so special<\/strong> is changing.<\/p>\n And it’s changing in ways we can do almost nothing about.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Alaska\u2019s 13-mile-long Mendenhall Glacier is no longer connected to the lake it created.
