Shadow Mountain Lookout, Fire lookout tower in Rocky Mountain National Park, Colorado, United States.

Shadow Mountain Lookout is a three-story structure near the summit of Shadow Mountain above Grand Lake. Its first two stories are stone masonry that appears to grow from a rock outcropping, while the frame third story carries a pyramidal roof. The building stands at an elevation of 9,923 feet.

The National Park Service built this fire detection tower in 1932 using workers from the Civilian Conservation Corps. This investment in fire surveillance was part of a broader effort to protect the park's forest resources.

The lookout reflects National Park Service design principles, where natural stonework blends seamlessly into the mountain landscape. The way the structure integrates with its surroundings shows a thoughtful approach to balancing human facilities with the natural environment.

The lookout is reached via the Shadow Mountain Trail, a hiking route listed on the National Register of Historic Places since 2008. The structure stands near the summit of Shadow Mountain at 9,923 feet, overlooking Grand Lake. The last summer season of use was 1978, so the building is not staffed today.

This structure is the sole surviving fire lookout in the entire park, while three others were removed from different mountain peaks. Its solitary survival makes it a special witness to the park's early fire protection history.
