Discussion in a tent at a remote lake led to a new look at Alaska tectonic activity 75 million to 50 million years ago, a period spanning the Late Cretaceous through the early Paleogene. The two geologists determined that the concurrent events of the Western Alaska rotation and Southeast Alaska metamorphism from the addition of crust created the curvature seen today — an orocline in geologic terms. It can be seen in the arc of the Alaska Range mountains, Wrangell Mountains and St. Elias Mountains and the southern coastline.
