The blue waters of Clear Lake, the largest freshwater lake entirely within the state of California, and the terrain of the Coast Range are apparent in this low-oblique, south-looking photograph. Visible are Clear Lake, a major tourist and fishing resort 25 miles (40 kilometers) long and 2 to 10 miles (3 to 16 kilometers) wide, and Lake Berryessa, another popular tourist resort, near the top left. Hogback ridges traverse north-south, and timber-covered Mendocino National Forest is visible near the bottom center to bottom right.
