oh, you thought you’d get away with not hearing about volcanoes, lava, and geothermal activity? HA! buckle up! 🌋 past MAR 436 trips have been able to witness lava flowing from active volcanoes, and we were able to drive past many lava fields - some only a couple years old! From pseudo-craters to legit ones, there’s a lot of cool places to see created by energy bubbling up from the mantle! And don’t get me started on basalt columns - want to know how they happen? There’s an explanation called ✨columnar jointing✨: as slow lava/magma/ash-flows cool, contraction of the material occurs and pockets form pulling in on themselves and fracturing from their kin of surrounding pockets in these kind-of-lava-fractals. Link here if you’d like to know more :) https://www.nps.gov/subjects/volcanoes/columnar-jointing.htm

hi there, Claire here :) This week we’ll be sharing some adventures from our Natural History of Iceland travel course! One of the many natural wonders we saw were glaciers. The first of which was Sólheimajökull (slides 1-6) - an incredible example of how glaciers carry sediments that accrue on their surface and as they flow. The second ice behemoth we got to visit was Langjökull (“long glacier” - Iceland’s second largest) where we took the truck in slide 7 and drove up onto the glacier before exploring within. There we saw fissures and moulins (aka “glacier mills” - drainage for melted surface ice) from below where the tunnels carved for tours interrupted their progression through the ice. 🧊 Stay tuned for more Iceland! 🇮🇸
