Middle Cave and Timpanogos Cave were discovered in an era where their formations and resources could be protected. The National Park Service, which oversees and preserves the cave complex, has continued to develop new ways to retain its natural features, including limiting lighting in the caves to retard growth of invasive organisms. Preservation is a high priority. The resource management team at the monument is actively involved in protecting the cave and its surroundings. The National Park Service is continually monitoring and striving to determine a successful balance between visitor access and cave preservation. A limited number of people per tour was implemented to help lessen the human impacts in the caves.
