Ridgefield is notable for the significant Native American and Lewis and Clark Expedition history of the area, but is also the home of the Ridgefield National Wildlife Refuge, a primary reserve for migrating waterfowl on the Pacific Flyway, and the Ridgefield High School "Spudders" (reflecting the area's potato-farming heritage). The city is home to several annual community events, such as their old-fashioned Fourth of July Celebration, and also holds a bird festival that attracts bird lovers from around the region and beyond.
While the town of Ridgefield is in itself relatively modest in size, the geographic area that is locally also called Ridgefield is quite a bit larger, extending from the Columbia River to its immediate west, the Lewis River to the north, several miles past Interstate 5 to the east, and south nearly to Vancouver, Washington, encompassing both the Clark County Fairgrounds  and the Amphitheater at Clark County .
The area has important ties to the Lewis and Clark Expedition of 1804–1806.
Ridgefield was an important trading center as early as the 1860s, and the city was officially incorporated on August 26, 1909. U-Haul, an American equipment rental company, had its start in Ridgefield in 1945. The community's ties to the Chinookan people was commemorated by the construction of a replica of a Cathlapotle plankhouse at the Ridgefield National Wildlife Refuge, which was dedicated March 29, 2005.
Ridgefield is located at (45.815309, -122.727846).
In the physical lay of the land, (old, pre-Growth Management Act) Ridgefield is like many towns up and down the Columbia River in that it essentially dead-ends at the river, although in this case it is an offshoot of the Columbia River, Lake River, that the city runs up to, about three miles (5 km) west of Interstate 5.
The area is marked, as one would expect, with numerous fields bordered by canyons, with ridges along them overlooking the canyons in places. The canyons have been and continue to be carved from the land primarily by water erosion. The land here has been cleared of much of its earlier forests to accommodate the uses of people, first as fields for farming, mostly potatoes and plums for prunes, and growth, especially residential development continues to impact the area.
