Alaska is so large and new, so unconquered and exquisitely real, as to defy summation. Natural forces of vast scale and subtlety were still shaping the land in their own way, inscribing a different story on each of an infinite number of unexpected places. Each region, whether populated or not, was unique far beyond my ability to explain.
In contrast to many places you might choose to visit, it's Alaska's unformed newness that makes it so interesting and fun. Despite the best efforts of tour planners, the most memorable parts of a visit are unpredictable and often unexpected: a humpback whale leaping clear of the water, the face of a glacier releasing huge ice chunks, a bear feasting on salmon in a river, a huge salmon chomping onto your line. You can look at totem poles and see Alaska Native cultural demonstrations, and you can also get to know indigenous people who still live by traditional ways. And sometimes grand, quiet moments come, and those are the ones that endure most deeply.
