In 1907, the first ascent of Mount Garibaldi was completed by Vancouver mountaineers A. Dalton, W. Dalton, A. King, T. Pattison, J. J. Trorey, and G. Warren. The views from the peaks inspired the establishment of summer climbing camps at Garibaldi Lake, which included among their ranks many members of the newly-formed British Columbia Mountaineering Club. The first of these camps resulted in the naming and first ascent of The Black Tusk, by a party led by William J. Gray in 1912. The interest sparked by the camps eventually led to the park being legislated as a park reserve in 1920, and designated as a Class A Provincial park in 1927.
