The starting point (east) has been closed since July.\u201d<\/em><\/p>\n\n\n\n The reason for this is the crevasses<\/strong> appearing on the glacier\u2019s eastern margin, which have made it impossible and not even permitted to go onto the glacier.<\/p>\n\n\n\n Crevasses on glacier margins are extremely common due to glacier movement,<\/strong> friction, and internal stresses.<\/p>\n\n\n\n Glaciers are always in motion, even though the movement is often slow and not visible to the naked eye.<\/p>\n\n\n\n Vatnaj\u00f6kull typically moves several hundred meters per year, but its fastest outlet glaciers can advance more than a kilometer annually.<\/p>\n\n\n\n We agreed that in spring 2027 I will first run across the Hofj\u00f6kull glacier, and from there we will continue onto the Langj\u00f6kull glacier.<\/p>\n\n\n\n In recent decades, Langj\u00f6kull has shrunk significantly due to climate warming, losing area and thickness faster than many other Icelandic glaciers.<\/p>\n\n\n\n Hofj\u00f6kull is Iceland\u2019s third-largest glacier, a domed ice cap with an active volcano beneath it.<\/p>\n\n\n\n Like the other Icelandic glaciers, Hofj\u00f6kull is also in a clear retreat phase and is rapidly losing area due to rising temperatures.<\/p>\n\n\n\n Cravasses, Vatnaj\u00f6kull 2025. We saw plenty of them especially on the western part of the glacier.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Tiimimme onnistui ylitt\u00e4m\u00e4\u00e4n Euroopan suurimman j\u00e4\u00e4tik\u00f6n (Vatnaj\u00f6kull) toukokuun 2025 aikana.
