Little Blue Peak is highest point on Little Blue Ridge in the Northern Coast Ranges of California. Despite its relatively low elevation, the officially unnamed summit, located on boundary between Yolo and Lake counties is the highest point in Yolo County. However, Little Blue Peak didn't always have that distinction, since Berryessa Peak 3,057 feet (932 m) was considered to be the Yolo County highpoint until 1991. That year John Sarna discovered this peak which is more than 80 feet (24 m) higher.
