The majority of the soils in Alaska are Gelisols which are mostly found in high latitude polar regions. There are types; "Histel gelisols contain large amounts of organic matter. Turbel gelisols are produced as a result of mixing by frost action. Orthel gelisols are the most common and are soils that do not meet the criteria for histel or turbel gelisols."(Ballard Coates). The soils in Alaska have more nutrients and less contamination compared to industrialized places.

Mountains
The mountains in the Brooks Range are made of sedimentary rock. In the Ogilvie Mountains a Karst topography is common and is made up of flat topped hills. The Ahklun and Kilbuck Mountains are rugged groupings of mountains that are steep and sharp. The Alaska Peninsula Mountains is made up of rounded, folded sedimentary rock. Some mountains are covered by ice fields and glaciers.
Climate
"Temperatures in Alaska during the summer range from 60°F-80°F. Nighttime and early mornings are cooler, from the 40's - 50's. Late August and September departures could encounter cooler temperatures and slightly fewer hours of sunlight, as fall arrives early at these latitudes.The Interior Region of Alaska enjoys warm summers.The Northern Interior (along Brooks Range) holds the record for the lowest temperature of -79.8° F" (Travel Alaska).
