3D-print demonstrating a rotational landslide at it simplest. Amazing how much you can actually communicate with such a simple model: Rotation, self-stabilization etc.
Working towards making more complex models and share the blueprints so they can be used in outreach.

The Semper Crevasses project is keeping us busy on the ice sheet this week! Here's the view into one of Greenland's newest crevasses, which has opened in recent months at 2000 m elevation above sea-level about 100 km inland from Ilulissat Glacier front.
