Mima Mounds Natural Area Preserve is a state-protected Natural Area in southwest Washington state, United States. The preserve includes some of the Washington mima mounds, the origin of which still is not fully understood. The site comprises 637 acres (258 ha) of Garry oak woodland, oak savanna, and prairie grasslands. Several state and federal endangered species of butterfly depending on the unique prairie conditions can be found in the preserve, including Mardon skipper, zerene fritillary, Puget blue and Taylor's checkerspot.In 1966, the mima mounds were designated a National Natural Landmark.

Scott Lake is a lake in Thurston County, Washington, United States. It is located 3.2 miles (5.1 km) south of the Tumwater city limits, 8.4 miles (13.5 km) south of the Olympia city limits, and 14.1 miles (22.7 km) north of the Centralia city limits. The location for Scott Lake is in Sections 33 and 34, Township 17N, Range 2W, Willamette Meridian.The lake receives its water from a creek that comes out of Deep Lake. The creek is officially unnamed, but is referred to as Spruce Creek by the Millersylvania State Park. The creek that flows out of Scott Lake is officially named Allen Creek. Allen Creek flows into Beaver Creek, a tributary of the Black River. Thus it is part of the Chehalis River watershed. A nine-hole golf course that is opened to the public, and a private park opened only to residents of the Scott Lake Community are located next to the lake. Eurasian water-milfoil (myriophyllum spicatum), an invasive species, was found in the lake in the spring of 1996.The area is subject to occasional flooding in winter. Its causes are being studied.

Salmon Creek is a stream in Thurston County in the U.S. state of Washington. It is a tributary to the Black River.Salmon Creek was so named on account of its stock of salmon.

Deep Lake is located in Section 3, Township 16N, Range 2W, Willamette. The lake is bordered on two sides by Millersylvania State Park. An RV resort camp occupies the lake's eastern shore.

Mima mounds are low, flattened, circular to oval, domelike, natural mounds that are composed of loose, unstratified, often gravelly sediment that is an overthickened A horizon. These mounds range in diameter from 3 to more than 50 m; in height 30 cm to greater than 2 m; and in density from several to greater than 50 mounds per hectare, at times forming conspicuous natural patterns. Mima mounds can be seen at the Mima Mounds Natural Area Preserve in Washington state. "Mima" is a name derived from a Chinook Jargon term meaning "a little further along" or "downstream".Theories for the origin of Mima mounds include burrowing by pocket gophers; accumulation of wind-blown (aeolian) sediments around vegetation to form coppice dunes or nebkhas; seismic ground shaking by major earthquakes, though none have been observed to form Mima mounds; and shrinking and swelling of clays in hog-wallow or gilgai landforms. Though the definitive Mima mounds are common in North America, it has not been shown that all North American mounds result from the same causes. Superficially similar phenomena occur on all continents, and the proposed causal factors do not occur in all regions that have been studied. Nor is it clear that all such mounds really are the same, either physically or functionally; for example, the so-called fairy circles of Southern Africa tend to be less mound-like and occur in different climatic and ecological conditions from Mima mounds. Furthermore, it has been argued that the possibly distinct heuweltjies of the South Western Cape region of South Africa are of an origin far different from either.

Prairie Creek is a stream in Thurston County in the U.S. state of Washington. It is a tributary to the Chehalis River.Prairie Creek was so named for the prairie near its course.
