Glaciar Viedma

Glaciers are geologic chaos, scraping and sliding stones and sediments of all sizes across the landscape. What's deposited in the morraine (the rocky glacial debris) is an unsorted array of boulders, stones, silt, sand, all the way down to fine glacial flour. The sediments are packed with mineral nutrients to feed the terrestrial and ocean ecosystems downstream. Across the southern Patagonia ice field, the glacial morraine leaves stripes of color like paint brush strokes, draining into milky mineral lakes.
