The Summit Lake Ranger Station, also known as the Summit Lake Patrol Cabin, is one of the first three buildings constructed by the National Park Service in Lassen Volcanic National Park, California. Located near the center of the park on the main park road, the cabin was built in 1926. It is a log building measuring about 20 feet (6.1 m) by 30 feet (9.1 m) with an asymmetric gable roof that results in a long pitch to a low rear wall. The main portion of the station comprises a living area, kitchen, and two bedrooms. A former porch has been enclosed and houses a bathroom.
