A Civilian Conservation Corps crew completed it in 1934 to National Park Service plans.","why_significant":"The nomination argues local architectural significance as an outstanding, essentially unaltered example of an NPS-designed rustic back-country log ranger station from the 1920s and 1930s. It also has local significance in social/humanitarian endeavor because it was built by the Civilian Conservation Corps. It keeps its integrity of design, material and site, and blends into its forest setting.","narrative":"Horseshoe Lake Ranger Station is a small log residence built in 1934 in the back country of Lassen Volcanic National Park. A Civilian Conservation Corps crew finished it on October 22, 1934, following National Park Service architectural drawings. It was meant to house a fireguard and has also been called a patrol cabin and fireguard station. The building measures roughly 33 by 23 feet and is made of peeled horizontal logs on a mortared stone foundation, with a hand-split shake roof, a stone fireplace and chimney, and a gabled front porch. Its only notable change is the conversion of the rear porch into a storage room. A matching frame barn has been removed. The station was listed because it is a well-preserved example of the rustic style that park architects used to make buildings blend with their surroundings, and because it shows what CCC crews could build. It is still used in summer.","period_of_significance":"1934","architect_builder":"National Park Service and CCC","architectural_style":"NPS rustic-style log building","criteria":[],"status_note":"Described as in excellent overall condition and essentially unaltered.
