Christmas Valley is a sparsely populated unincorporated community in Lake County, Oregon. It is located in the high desert, characterized by a semi-arid climate with long, hot summers and cold, snowy winters. The area is situated in a basin, with a shallow groundwater system that is heavily influenced by irrigation. As a result, hydrology constituents, such as nitrates and phosphorus, are often found in the groundwater. The landscape is dominated by vast stretches of sagebrush and juniper, with several natural attractions, including the Crack in the Ground, Fort Rock State Natural Area, and the Christmas Valley Sand Dunes. Outdoor recreation opportunities include hiking, fishing, hunting, and off-roading in designated areas.
