The stark beauty of a land shrouded in ice, bordering the ocean, and teeming with wildlife covers a plot taking place underneath it all. Beneath the splendor, larger forces are at work. The movement of tectonic plates and the delivery and formation of various rock types prescribe where birds nest, where Steller sea lions breed, and where glaciers flow. The varying rock of the fjords underwrites the spectacle seen above- in one place eroding into graceful arches, in another withstanding the ocean's constant blows. Crustal Collision Plate tectonics theory describes how the Earth is put together, and how it changes over time. The center of the Earth is a tremendously hot core of iron and nickel.

Green and greenish rocks get their color from minerals that contain iron or chromium and sometimes manganese. The most widespread green mineral, chlorite is rarely present by itself. In microscopic form, it gives a dull olive green color to a wide range of metamorphic rocks from slate and phyllite to schist.
It lies fewer than forty road miles about an hour from Fairbanks and is easily accessible by car. The White Mountains encapsulate true Alaskan wilderness right on the backdoor of Fairbanks. One of the most popular hikes in the area is Wickersham Dome on Summit Trail, which travels along ridges and above treeline atop packed dirt and exposed rock with a panoramic picture of the White Mountains and as far north as the Brooks Range on a clear day. Wickersham Dome is one of the most notable vantage points along the route, in the form of a rounded hilltop in the southwest corner of the wilderness area with little in the way to obstruct the views. Berry-picking is also popular here in late summer.
