The Alder Springs Fire has grown to well over 600 acres. Bill Queen is the Public Information Officer for the Central Oregon Interagency Dispatch: "Current estimate is between 650 and 700 acres. The fire is burning in a mosaic of grass, shrubs and scattered timber. While several private ranches and Crooked River Ranch remain threatened to the east, initial attack efforts have prevented any loss of structures." Queen says they are planning more aerial reconnaissance today to better map the fire and survey any fire closure needs. Right now, the Alder Springs Trailhead and trail and Forest Road 6360 are closed. Unseasonable high temperatures and low humidity caused the fire to spread quickly yesterday, and today's weather is predicted to be the same.
