Mount Stephen

Mount Stephen, 3,199 m (10,495 ft), is a mountain located in the Kicking Horse River Valley of Yoho National Park, 1⁄2 km east of Field, British Columbia, Canada. The mountain was named in 1886 for George Stephen, the first president of the Canadian Pacific Railway. The mountain is mainly composed of shales and dolomites from the Cambrian Period, some 550 million years ago. The Stephen Formation, a stratigraphical unit of the Western Canadian Sedimentary Basin was first described at the mountain and was named for it. Stephen has a subpeak known as Stephen SE1, at the end of a 1 km ridge, 132° from the main peak, visible from Lake O'Hara.
