"One of the few native grassland prairies left in western Washington is contained in the 445-acre Mima Mounds Natural Area Preserve. This prairie and the mysterious origins of the roughly 6-foot-tall mounds are enough to draw thousands of annual visitors to this small preserve, but it also holds some of the best birding, butterfly-watching, and wildflower gazing in the southern reaches of the Puget Trough. After a short walk through the wooded area, the trail leads to a large man-made concrete mound that offers information about the site as well as a viewing platform at the top of the stairs. Scanning the prairie from the top of the stairs will give a good indication of what birds are around before you set out on either the 0.5-mile interpretive trail or one of the longer and more rustic trails into the prairie. Habitats: Prairie, coniferous forest. Specialty birds: White-tailed Kite; Bald Eagle; Peregrine Falcon; Band-tailed Pigeon; Shorteared and Northern Pygmy-Owls; Vaux’s Swift; Rufous Hummingbird; Pileated Woodpecker; Red-breasted Sapsucker; Pacific-slope Flycatcher; Hutton’s and Cassin’s Vireos; Western Bluebird; Hermit Warbler."

"Lightning- induced fires and poor soils derived from a thick mix of glacial sand and gravel have produced many treeless prairies south of Olympia. The Mima Mounds prairie is one of the most notable examples. In 1967 the Mima Mounds was designated a national natural landmark by the National Park Service. It wasn’t until 1976 that Washington State designated the 637-acre natural area preserve. The purpose is to protect the Mima mound landforms and prairie grasslands and to provide habitat for prairie- dependent birds and butterflies such as the endangered Mardon skipper (Polites mardon), Zerene fritillary (Speyeria zerene), Puget blue (Icaricia icarioides blackmorei), and Taylor’s checkerspot (Euphydryas editha taylori)."

We hiked the Mima Falls trail. 5 miles out and back. Worth every step. The waterfall at the end was so beautiful. Sat and had lunch next to it. Lots of horse poo. Saw salamanders in the river but not many birds.
