The Carmelite Monks or Monks of the Most Blessed Virgin Mary of Mount Carmel are a public association within the Diocese of Cheyenne, dedicated to a humble life of prayer. The Wyoming Carmelites claim loyalty to the Magisterium of the Catholic Church and to the Carmelite charism. Their life includes strict separation from the world and the living of the cloistered Carmelite spirituality and way of life established by John of the Cross and Teresa of Jesus. In accord with the Carmelite Rule, they engage in manual labor and the study of Carmelite spirituality in the solitude of the mountains, with the firm hope of attaining to Union with God.

Enclosed religious orders are religious orders whose members strictly separate themselves from the affairs of the external world. The term cloistered is synonymous with enclosed. In the Catholic Church, enclosure is regulated by the code of canon law, either the Latin code or the Oriental code, and also by the constitutions of the specific order. It is practised with a variety of customs according to the nature and charism of the community in question. This separation may involve physical barriers such as walls and grilles, with entry restricted for other people and certain areas exclusively permitted to the members of the convent. Outsiders may only temporarily enter this area under certain conditions. The intended purpose for such enclosure is to prevent distraction from prayer and the religious life and to keep an atmosphere of silence.
