Editing Fort Wainwright (section)

==Geography==
=== Location ===
Fort Wainwright is located in [[Interior Alaska]], between the [[Alaska Range]] in the south and the [[Brooks Range]] in the north. Fort Wainwright's boundaries are located within the Fairbanks North Star Borough. To the west is the City of Fairbanks, and to the southeast is the City of [[North Pole, Alaska|North Pole]]. Fort Wainwright resides on both sides of the Chena River, a 100-mile tributary of the Tanana River.

=== Demographics ===
The total population to include the workforce on Fort Wainwright is approximately 15,000 personnel. There are roughly 6,500 military members, 5,700 military dependents, 1,250 civilian employees including appropriated and non-appropriated fund employees and over 400 contractors.{{citation needed|date=December 2021}}

=== Climate ===
Fort Wainwright is located in a subarctic climate with seasonal temperature extremes. Temperature extremes have been recorded from −66&nbsp;°F to +94&nbsp;°F (−54&nbsp;°C to +34&nbsp;°C). The average low temperature is in January at −17&nbsp;°F (−27&nbsp;°C) with the average high temperature is during July at +73&nbsp;°F (+22&nbsp;°C). The annual precipitation averages 12 inches (305&nbsp;mm) of rain and 37 inches (94&nbsp;cm) of snow. Fort Wainwright is approximately 190 miles south of the Arctic Circle. The hours where the sun is above the horizon averages 22 hours in June with twilight during the night hours and less than 4 hours in December. The climate creates a short construction season for installation projects. It also potentially contributes to Seasonal Affective Disorder (SAD) among the workforce.{{citation needed|date=December 2021}}

=== Geology ===
Fairbanks falls in a region with discontinuous permafrost, a condition where permafrost is broken by pockets of unfrozen ground. This, coupled with the periglacial effect of seasonal freezing and thawing, can drastically modify the ground surface. Construction engineering in this environment requires additional planning to avoid the potential for hazards of ground movement or collapse.
