Diadem Peak is located in Jasper National Park. It is situated in the Winston Churchill Range between the Athabasca and Sunwapta Rivers. Diadem is immediately north of Mount Woolley, west of Mushroom Peak, and northeast of Mount Alberta. Diadem can be seen from the scenic Icefields Parkway (Highway 93), and an even better view is obtained from Tangle Ridge. The Gong Glacier is positioned 500 meters below the steep northeast face of the mountain. Diadem Peak is named for the diadem, or crown, of snow on the flat summit.
Refer to Selected Alpine Climbs in the Canadian Rockies by Sean Dougherty for information on the climbing routes on Diadem Peak.
