The National Park Service is continuing its tradition of voluntarily closing all climbing routes on Devils Tower for the month of June.
NPS officials said the month holds spiritual and cultural significance for many Native American tribes closely associated with the monument.
Out of respect for these tribes the NPS has implemented a voluntary closure on Mato Tipila - Bear Lodge (Devils Tower) in June since 1996.
Climbers are encouraged to explore other climbing sites in the region during the month such as Mt. Rushmore Needles, Custer State Park, and Spearfish Canyon.
