It is notable that the landslide spread out both upstream and downstream of the junction with the main channel.\u00a0 Some erosion of the landslide track can now be seen as well.\u00a0 The original landslide mass would have comprised of both ice and sediment; the former will now be thawing, leaving just the mineral matter in the valley.<\/p>\n<p>The reasons for this large glacial landslide remains unclear, but <a href=\"https:\/\/blogs.agu.org\/landslideblog\/2017\/09\/12\/rock-avalanche-alaska\/\">large rockslides and glacial landslides are becoming more common<\/a> as the climate change crisis rapidly increases rates of melting on glaciers and in permafrost slopes around the world.<\/p>\n<h4>Reference and acknowledgement<\/h4>\n<p>Thanks to Robert Simmon, Senior Data Visualization Engineer, and his colleagues at Planet Labs for capturing this image and for processing it.<\/p>\n<p>Planet Team (2018).
