Wild Basin Ranger Station, in the southeastern part of Rocky Mountain National Park in Colorado, was built in 1932 as a small ranger station with both administrative and residential space and remains in use as a Passport to Your National Parks cancellation location. Designed by the National Park Service Branch of Plans and Design, it is a clear example of National Park Service rustic architecture. The log building has a concrete foundation, wood shingles, a steep gable roof, and a porch supported by corbeled logs. Its importance rests in how well it expresses the early 20th-century park service style meant to blend with the mountain landscape.
