Lassen Peak Manzanita Lake.
Manzanita Lake is a lake located in Lassen Volcanic National Park. Located near the park entrance, the lake is open for fishing and has rainbow, brown and brook trout.
Manzanita Lake was formed when Manzanita Creek was dammed 300 years ago by a rock avalanche from the northwest slope of the Chaos Crags, which also resulted in the debris formation known as Chaos Jumbles.
The area around the lake features the Loomis Museum, a campground, and the Manzanita Lake Naturalist's Services Historic District.
