Gray-green Eagle Lake is visible in this low-oblique, southwest-looking photograph. Located east of Lassen Peak Volcano, Eagle Lake sits on a semiarid, high volcanic plateau. The lake, fed by Pine Creek that originates near Lassen Peak and enters near the northwest center of the lake, empties into Willow Creek on its southeast side. Surrounding the lake are volcanic mountains—Fredonyer Peak east of the lake and Crater Mountain northwest of the lake near the top right of the photograph. The small city of Susanville near the center of the photograph; tan Horse Lake, normally a dry lake, southeast of Fredonyer Peak near the bottom left; and snow-covered Lassen National Forest to the west are discernible.
