new highway route was needed. In 1963, the Trans-Canada Highway was built through Rogers Pass, bringing tourists back to the park in large numbers. Parks Canada built several new campgrounds and expanded the trail system. Geography The park covers the northern part of the Selkirk Mountains, a sub-range of the Columbia Mountains. It contains numerous glaciers and large, swift waterways. The park is bisected by two major transportation routes, the Trans-Canada Highway and the Canadian Pacific Railway. The nearest towns are Revelstoke to the west, and Golden to the east. Mountains The Columbia Mountains rise from the plateaus of the Central Interior and extend eastward to the Rocky Mountain Trench. Geologically distinct from the nearby Rockies, the range is divided into four sub-ranges: the Cariboos, Monashees, Selkirks, and the Purcells. Glacier encompasses a portion of the northern Selkirks and a narrow strip of the northern Purcells. The topography of the park varies between rounded mountains and ridges in the east, north, and west, and sharp, steep-sided peaks in the central and southern regions. A.O. Wheeler measured many of the park's mountains in 1901 and 1902 using a complex system of fixed points and photographs. In the early 20th century, the area was referred to as the "Canadian Alps". Most names are from historical figures, including explorers, surveyors, mountaineers, and railway and Hudson's Bay Company executives. Major peaks and ranges The highest point in the park is Mount Dawson, at . The precipitous Mount Sir Donald stands at , Mount Macdonald at , Mount McNicoll at , and Mount Abbott at . Peaks of the Hermit Range, the Bonney and Bostock Groups, the Van Horne Range, Purity Range and the Dawson Range, all lie wholly or in part within the park, including Uto Peak at in the Sir Donald Range. Glaciers The park has 131 glaciers over in size, covering of the park. Throughout its history, North America has seen cycles of glaciation, where ice sheets advanced and retreated across the terrain. The last glacial period ended about 12,000 years ago, before which all but the highest peaks of the park were covered in ice. The movements of these rivers of ice formed the steep-sided, U-shaped valleys of the park. They also rounded the lesser peaks; ranges in the west of the park show this effect. The glaciers in the park are on whole shrinking and retreating; they are also some
