Its walls are milled planks laid flat with extended butt-joint corners, as in log cabin construction, a method described as the only known example of its kind in Western Region park areas. It was also one of the first three buildings the National Park Service erected in the park in 1926.","narrative":"Warner Valley Ranger Station is a small two-story building in Lassen Volcanic National Park, north of Chester in Plumas County, California. Built by the National Park Service in 1926 and rebuilt in 1927 after heavy snow damaged it, it measures about 24 feet square. Its walls are milled lumber planks laid flat, one on another, with extended butt joints at the corners, an adaptation of log cabin building to sawn lumber. The nomination calls this the only known structure of that type in National Park Service areas in the Western Region, and suggests the method may have been chosen because it needed less labor in a timber-rich area. The station was among the first three buildings the Park Service put up in the park, alongside ranger stations at Summit Lake and Butte Lake. It has served part of each year as a ranger's residence and is closed in winter. A stone fireplace, a corrugated metal roof added in 1967, and a 1935 garage and barn complete the site.","period_of_significance":"1926 - Present","architect_builder":"National Park Service","architectural_style":null,"criteria":[],"status_note":"Listed in excellent condition and largely unaltered since 1927; used part of each year as a ranger residence and closed and empty in winter.
