Renowned for their scenic splendor, the Canadian Rocky Mountain Parks are comprised of Banff, Jasper, Kootenay and Yoho national parks and Mount Robson, Mount Assiniboine and Hamberprovincial parks. Together, they exemplify the outstanding physical features of the Rocky Mountain Biogeographical Province. Classic illustrations of glacial geological processes - including icefields, remnant valley glaciers, canyons and exceptional examples of erosion and deposition - are found throughout the area. The Burgess Shale Cambrian and nearby Precambrian sites contain important information about the earth’s evolution.
Located at 110-180km west of Calgary, Banff National Park is Canada's oldest national park, established in 1885. Named for an early trail guide and trapper in this area and located in Banff National Park, Peyto Lake(in the first postcard) is a glacier-fed lake formed in a valley of the Waputik Range, between Caldron Peak, Peyto Peak and Mount Jimmy Simpson, at an elevation of 1,860m. During the summer, significant amounts of glacial rock flour flow into the lake, and these suspended rock particles give the lake a bright, turquoise colour. The lake is fed by the Peyto Creek, which drains water from the Caldron Lake and Peyto Glacier (part of the Wapta Icefield), and flows into the Mistaya River.
One of the icefield of Canadian Rocky Mountain Parks is Columbia Icefield, which lies partly in the northwestern tip of Banff National Park and the southern end of Jasper National Park. It is about 325 km² in area, 100 to 365m in depth and receives up to 7m of snowfall per year. The icefield feeds eight major glaciers, including Athabasca Glacier (in the second postcard). It currently recedes at a rate of about 5m per year and has receded more than 1.5km in the past 125 years and lost over half of its volume. The glacier moves down from the icefield at a rate of several centimetres per day. Due to its close proximity to the Icefields Parkway, between the Alberta towns of Banff and Jasper, and rather easy accessibility, it is the most visited glacier in North America.
