The Thunder Lake Patrol Cabin is a small structure in Rocky Mountain National Park, Colorado. Built in 1930, the 12-foot (3.7 m) by 16-foot (4.9 m) cabin may have been built as a simple shelter, but has more recently been used on an occasional basis as a backcountry patrol cabin in the Wild Basin area. The one story one-room log cabin is not used in the winter, but does have a stove with a stone fireplace. The main cabin is gable-roofed, with a small shed-roofed porch, and is a good example of the National Park Service rustic style. The logs are saddle-notched, projecting an increasing distance at their ends from top to bottom.
