Olmstead Place features a working pioneer farm and hosts tours and school field trips. The site is one of the first homesteads in the Kittatas Valley. Several historic buildings remain standing at Olmstead Place including a log cabin built in 1875. It was constructed of cottonwood logs from the Yakima River Canyon. The cabin is furnished with articles used in pioneer days by the Olmstead family.
