The National Park Service (NPS) has reviewed and updated the Devils Tower National Monument 1995
Climbing Management Plan (CMP). Primary features of the CMP Update are an improved climber
education program, safety standards and climbing access routes, as well as a continued June voluntary
climbing closure. Other elements of the 1995 CMP remain valid including: seasonal falcon climbing
closure, bolt replacement allowed/no new bolting, hammers allowed/no power drills.
The CMP Update process began with a public comment period held from May 15 to July 15, 2002, during
which 39 comments (33 from individuals and 6 from organizations or companies) were received. A
March 17, 2003 newsletter provided an update on the CMP Update process to interested parties. After
considering the public response, comments received from affiliated Native American tribes and effects to
resources, the NPS has selected the following actions for the CMP Update:
Safety Standards
The National Park Service will be requiring commercial guides to be certified by the American Mountain
Guides Association or equivalent organization that trains and tests guides for competency. This standard
will improve safety for guided climbers which make up about 40% of Tower climbers.
Climbing Access Routes
Climbing access route maintenance will be completed to repair route erosion and eliminate social routes.
Climbers will continue to be required to pack human waste off approach routes and the Tower. Human
waste bag systems will continue to be sold at the bookstore in the visitor center.
June Voluntary Climbing Closure
The NPS will continue a voluntary climbing closure on Devils Tower during the month of June when
many Native American traditional cultural activities occur at the Tower. This voluntary closure has been
in effect each June since 1995 when a CMP was established.
