Locos por la Geología

Once again I share a wonderful text written by Charlotte Gill, and selected from her book Eating Dirt.

Fourteen thousand years ago, this land was buried in Pleistocene ice. The ecosystems underneath flattened, scree-strewn, beaten down under the weight of glaciers. A few millennia later the ice receded, and life crept back in from the fringes. Lodgepole pine edged north from California. A few thousand years after that, as the climate cooled and moistened, Douglas-fir and Sitka spruce took over. And then, about the time humans took up agriculture, the monsoons came up to visit the Pacific Northwest.
