Renowned for their scenic splendor, the
Canadian Rocky Mountain Parks are
comprised of
Banff, and
Jasper parks in Alberta, and
Kootenay,
Yoho,
Mount
Robson,
Mount
Assiniboine and
Hamber parks in British Columbia. 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.

1947 Banff National Park - Lake Louise |
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,
Peyto Lake 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, and flows into the Mistaya River.
Lake Louise, named Lake of the Little Fishes by the
Stoney Nakota First Nations people, is also a
glacial lake within the same park, drained through the 3 km long Louise Creek into the
Bow River, and having characteristics similar to Peyto Lake.

1184 Jasper National Park - Athabasca Glacier |
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. 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.

1775 Jasper National Park - Maligne Lake |
Jasper National Park is the largest
national park in the
Canadian Rockies, and includes the glaciers of the Columbia Icefield, hot springs,
lakes,
waterfalls and
mountains. Located 44km south of Jasper town,
Maligne Lake (from the French word for malignant or wicked) is famed for the colour of its water, the surrounding peaks, the three glaciers visible from the lake and Spirit Island. It is fed and drained by the
Maligne River, which enters the lake on its south side, near
Mount Unwin and drains the lake to the north.
Spirit Island is a tiny tied island, frequently photographed, a view which many people associate with the Canadian Rockies.

2923 Yoho National Park - Emerald Lake |
Located in southeastern British Columbia
, Yoho National Park was named after a
Cree expression of awe and wonder.
Emerald Lake is the largest of Yoho's 61 lakes and ponds, as well as one of the
park's premier tourist attractions. It is enclosed by mountains of the
President Range, as well as
Mount Burgess and
Wapta Mountain.
This basin traps storms, causing frequent rain in summer and heavy
snowfalls in winter. This influx of moisture works with the lake's low
elevation to produce a unique selection of
flora. Due to its high altitude, the lake is frozen from November until June.
The vivid turquoise color of the water, caused by powdered limestone, is
most spectacular in July as the snow melts from the surrounding
mountains.

2934 Yoho National Park -
A fossil of Bathyuriscus rotundatus |
The
Burgess Shale, located in Yoho National Park, has among the world's richest deposits of rare fossils.
Bathyuriscus is an extinct
genus of
Cambrian trilobite. It was a nektobenthic predatory carnivore. The genus Bathyuriscus is endemic to the shallow seas that surrounded
Laurentia. Its major characteristics are a large forward-reaching
glabella, pointed pleurae or pleurae with very short spines, and a medium
pygidium with well-impressed furrows.In Greek,
bathys means deep, and
oura - tail, so
Bathyuriscus means a trilobite with a deep tail. On the other hand,
rotundatus comes from the Latin
rotundus - round, presumably alluding to the rounded outline of the dorsal shield.
