Editing Fort Lewis (Washington) (section)

==Geography==
According to the [[United States Census Bureau]], the CDP has a total area of 15.9 square miles (41.2&nbsp;km<sup>2</sup>), of which 15.3 square miles (39.6&nbsp;km<sup>2</sup>) are land and 0.6 square miles (1.6&nbsp;km<sup>2</sup>) are water. The total area is 3.78% water. The military base is, as previously stated, much larger than the CDP defined by the Census Bureau.

Fort Lewis' terrain is primarily a mixture of dense conifer woods and open Puget prairie-[[garry oak]] woodlands. Invasive [[Scotch Broom]] has taken over many areas. The landscape is very rocky from glacial meltwater deposits. [[Toxicodendron diversilobum|Poison oak]] is found in the training areas. [[Canada Thistle]] grows thickly in some areas. All trees are to be left standing; post policy prohibits cutting or trimming them.

The temperatures during summer vary from the mid-40s at night to the mid-70s during the day, occasionally peaking over {{convert|90|°F|°C|abbr=on}}. Although July and August are the driest months.

Fort Lewis, due to its size and reserved land, serves as an important habitat for amphibian development and study.<ref>{{Cite journal|last=Adams|first=Michael J.|last2=Bury|first2=R.
