This morning we disembarked at Lake Eva on Baranof Island, where we fanned out for hikes through the old growth forest and kayaking through the salmon- and Dungeness crab-filled estuary. My group devoted all morning to the long trek up to Lake Eva itself, along the way pausing riverside to watch salmon swirl in an eddy under the roots of old growth trees they help nourish. These pink salmon (aka “humpies”) are making their way up their natal stream – remarkably, after hundreds or even thousands of miles journeying through the North Pacific Ocean, salmon return to the very stream where they hatched in gravel beds 2-7 years before. Now they will never to see the ocean again. Done eating, they are using every ounce of stored energy to fight the current upstream to spawn and usher forth the next generation, their final act. Farther up the trail, we encountered a grove of huge old-growth Sitka spruce. We craned our necks upward, and wondered at their antiquity. Speaking to the group about the history of logging on the Tongass National Forest, I guessed this tree was at least 500 years old, having germinated before the English language was ever spoken in western North America.
