The museum was built in 1923 by Imogene Green MacPherson as the center of her private tourist development, and was then known as the Moraine Park Lodge.

Both structures adhere to the National Park Service Rustic design ethic of the time, with stone and log construction.

Mrs. MacPherson continued to operate the resort after the death of her husband in 1919, and was involved in the campaign for the establishment of Rocky Mountain National Park.

The museum features interactive natural history exhibits, with themes including geologic processes, glaciation, weather and climate, ecosystems, and human impact.
