From their website:
In 1911, the General Young Women Presidency made a decision to find a summer camp for young women to get away from the valley heat and provide a retreat. In 1918, a search began for the perfect spot in which a summer home could be made and Brighton was selected. Brighton was completed and dedicated by Heber J. Grant in 1921.  Brighton has a very rich pioneer heritage and coming to camp makes you a part of Brighton’s continuing history.

Located at Brighton in Big Cottonwood Canyon.
