Last week, we travelled to Acadia National Park. We arrived at the summit of Cadillac Mountain after the sun had passed below the horizon. Most come here for the views, but an amazing ecosystem is right at your feet. With such a harsh environment of extremes in temperature, humidity, wind, and light, it would appear Mt. Dessert Island would earn its name. But life is everywhere. Ground-hugging plants have colonized every trough of dirt and the rock has gained blankets of lichen.
