Geography

Distribution of Periglacial Landforms in High-Latitude Regions

Quick fact

Individual ice wedges in high-latitude permafrost can be wider than a car and hundreds of metres long; when the ice melts, the ground above it collapses into repeating polygon-shaped troughs.

Why this is interesting

The Arctic ground isn't just frozen dirt—it actively sculpts its own surface into giant stone polygons, heaving mounds, and lakes that can disappear overnight. What makes these strange landforms cluster so strongly in the far north?
