Glacial Milk: Rivers That Color Lakes
Have you ever wondered what gives some mountain lakes their stunning, opaque turquoise color? The secret lies in "glacial milk", a cloudy meltwater rich with fine rock flour ground from…
The Albedo Effect: Earth’s Reflectivity
Not all surfaces are created equal when it comes to heat. We explore the Albedo effect—the measure of a surface's reflectivity—and how its geography, from the brilliant white ice caps…
Katabatic Winds: Gravity’s Icy Breath
Discover the powerful, gravity-driven winds that form when cold, dense air pours down from high elevations. We journey from the ferocious gales of Antarctica's ice sheets to California's infamous Santa…
The Lost Geography of Gondwana
Ever wondered why the coast of Brazil seems to fit so neatly against Africa? This is just one clue to a lost world—the ancient supercontinent of Gondwana. Journey with us…
Subglacial Lakes: Worlds Under Ice

Palynology: Recreating Lost Landscapes
Ancient pollen grains, preserved for millennia in sediment, are microscopic time capsules. Scientists use palynology (the study of pollen) to reconstruct past climates and landscapes, track the spread of human…
Glacial Mills (Moulins): Rivers Through Ice
Explore the fascinating world of moulins, the near-vertical shafts that funnel meltwater from a glacier's surface to its base. These "glacial mills" act as a powerful lubricant, dramatically reducing friction…
Periglacial Landscapes: Beyond the Ice
Beyond the colossal power of glaciers lies a subtler, yet equally dramatic world. These are the periglacial landscapes, found at the frigid edges of ice sheets and in the vast…
