2017 Map of Fort Lewis

About this map

Fort Lewis and the surrounding Pierce County landscape are defined by a complex network of glacial lakes and military infrastructure. The sprawling installation centers on Gray Army Airfield and the residential core of North Fort Lewis, while residential pockets like Tillicum and American Lake Garden Tract border the prominent American Lake. The terrain is characterized by a high density of named hills, such as Miller Hill and Davis Hill, which are interspersed among sensitive wetlands including Mackay Marsh and Elliot Marsh. To the south, the landscape opens into the Ninety-first Division Prairie, where smaller water bodies like Muck Lake and Chambers Lake drain toward Muck Cr. This 2017 survey reflects the modern configuration of one of the Pacific Northwest's most significant military corridors, balancing active training grounds with established communities like Hillhurst and Roy.
