“Meanwhile, hemlocks kept their footings in the deep, shady wrinkles of lower mountain slopes— coves shaped by intimate creeks and gorges carved by thundering rivers. Even east of the mountains, hemlocks survived on steep, north- facing slopes. In all of these places, microclimates continued to mimic conditions experienced in the region during the ice age. These isolated pockets are the last vestiges of a forest that once covered much of the Southeast. They are refugia.” — Ryan Emanuel
