Welcome to the I Can't Sleep Podcast, Where I help you drift off one fact at a time. I'm your host Benjamin Boster and tonight's episode is about Banff National Park. Thank you to Chris Thompson for sponsoring today's episode. The dedication reads, Happy birthday, Steffi. Love, Chris and Molly. Banff National Park is Canada's first national park, Established in 1885 as Rocky Mountains Park. Located in Alberta's Rocky Mountains, 110 to 180 kilometers, Or 68 to 112 miles west of Calgary, Banff encompasses 6, 641 square kilometers, Or 2, 564 square miles of mountainous terrain. With many glaciers and ice fields, Dense coniferous forest and alpine landscapes. It is bordered by Jasper National Park to the north. Yoho National Park and Kootenay National Park to the west in British Columbia, And Kananaskis Country to the southeast. The main commercial center of the park is the town of Banff in the Bow River Valley. The mountains were formed from sedimentary rocks that were pushed east over newer rock strata between 80 million and 55 million years ago. Over the past few million years, Glaciers have, At times, Covered most of the park. Glaciers are now found only on the mountain slopes, Including the Columbia Ice Field, The largest uninterrupted glacial mass in the Rockies. Erosion from water and ice have carved the mountains into their current shapes. Banff National Park has a subarctic climate with three ecoregions, Including montane, Subalpine, And alpine. The forests are dominated by lodgepole pine at lower elevations, And Engelmann spruce in higher ones below the tree line, Above which is primarily rocks and ice. Mammal species such as a grizzly bear, Cougar, Wolverine, Elk, Bighorn sheep, And moose are found, Along with hundreds of bird species. Before the park was established, The Stoney, Nakoda, And other indigenous people lived in the area, Where they maintained subsistence uses including hunting. In 1875, The Canadian Pacific Railway began construction of a transcontinental railroad through the park. Canadian Pacific Railway was instrumental in Banff's early years, Building the Banff Springs Hotel and Chateau Lake Louise, Which attracted tourists. Since the 1960s, Park accommodations have been open all year, With annual tourism visits to Banff increasing to over 4. 5 million as of 2025. Archaeological evidence found at Vermilion Lakes indicates there was human activity in Banff as early as 10, 300 BP. Prior to European contact, The area that is now Banff National Park was home to many indigenous peoples, Including the Stony Nakoda, Ktoonaha, Tsutina, Kainaiwa, Pikani, Siksika, And Plains Cree. Indigenous peoples utilize the area to hunt, Fish, Trade, Travel, Survey, And practice culture. Many places within Banff National Park are still known by their stony Nakoda names, Including Lake Minnewanka and the Waputik Range. In the 19th century, The Banff Bow Valley was of particular significance to the Nakoda people, Who moved seasonally through the region to hunt, And for other subsistence uses of the land. The area was also important to the Nakoda for spiritual and cultural reasons, Including the thermal hot springs at Cave and Basin. As the fur trade expanded westward, David Thompson of the Northwest Company crossed House Pass in 1807. In 1841, The Hudson's Bay Company Governor, George Simpson, Traveled up the Bow Valley and crossed the Simpson Pass. Between 1857 and 1860, The Palliser Expedition conducted scientific surveys in the region. In 1858, Geologist James Hector explored the Bow Valley and crossed both the Vermilion Pass and Kicking Horse Pass. As a condition for British Columbia joining the Canadian Confederation in 1871, Canada agreed to build a transcontinental railroad to connect the province to Eastern Canada. Construction of the railroad began in 1875, With kicking horse paths chosen over the more northerly Yellowhead Paths as a route through the Canadian Rockies. Ten years later, On November 7th, 1885, The last spike was driven in Cregillachie, British Columbia. In 1883, During construction of the railroad, Workers encountered the hot springs, And this led to government interest in conflicting claims over the hot springs. In 1885, Prime Minister John A. Macdonald decided to set aside a small reserve of 26 square kilometers, Or 10 square miles, Around the hot springs at Cave and Basin as a public park known as the Banff Hot Springs Reserve. Under the Rocky Mountains Park Act, Enacted on June 23, 1887, The park was expanded to 674 square kilometers, Or 260 square miles, And named Rocky Mountains Park. This was Canada's first national park, And the third established in North America after Yellowstone and Mackinac National Parks. The Canadian Pacific Railway built the Banff Springs Hotel and Lake Louise Chalet to attract tourists and increase the number of rail passengers. By 1911, Banff was accessible by automobile from Calgary. Beginning in 1916, The Brewsters offered motor coach tours of Banff. In 1920, Access to Lake Louise by road was available, And the Banff-Windermere Road opened in 1923 to connect Banff with British Columbia. In 1902, The park was expanded to cover 11, 400 square kilometers, Or 4, 400 square miles, Encompassing areas around Lake Louise and the Bow, Red Deer, Kananiskis, And Spray Rivers. Bowing to pressure from grazing and logging interests, The size of the park was reduced in 1911 to 4, 663 square kilometers, Or 1, 800 square miles, Eliminating many eastern foothills areas from the park. Park boundaries changed several more times up until 1930, When the area of Banff was fixed at 6, 697 square kilometers, Or 2, 586 square miles, With the passage of the National Parks Act. The Act, Which took effect May 30, 1930, Also renamed the park Banff National Park, Named for the Canadian Pacific Railway Station, Which in turn was named after the Banffshire region in Scotland. Was the construction of a new east gate in 1933. Alberta transferred 0. 84 square kilometers or 0. 32 square miles to the park. This, Along with other minor changes in the park boundaries in 1949, Set the area of the park at 6, 641 square kilometers, Or 2, 564 square miles. At the beginning of the 20th century, Coal was mined near Lake Minnewanka in Banff. For a brief period a mine operated at Anthracite, But was shut down in 1904. The Bankhead Mine at Cascade Mountain was operated by the Canadian Pacific Railway from 1903 to 1922. In 1926, The town was dismantled, With many buildings moved to the town of Banff and elsewhere. In 1931, The Government of Canada enacted the Unemployment and Farm Relief Act, Which provided public works projects in the national parks during the Great Depression. In Banff, Workers constructed a new bathhouse and pool at Upper Hot Springs to supplement cave and basin. Other projects involved road building in the park, Tasks around the Banff townside, And construction of a highway connecting Banff and Jasper. In 1934, The Public Works Construction Act was passed, Providing continued funding for the Public Works Project. New projects included construction of a new registration facility at Banff's East Gate and construction of an administrative building in Banff. By 1940, The Icefields Parkway reached the Columbia Icefield area of Banff and connected Banff and Jasper. Most of the infrastructure present in the National Park dates from public work projects enacted during the Great Depression. Winter tourism in Banff began in February 1917 with the first Banff Winter Carnival. It was marketed to a regional middle-class audience and became the centerpiece of local boosters aiming to attract visitors, Which were a low priority for the Canadian Pacific Railway. Carnival events included cross-country skiing, Ski jumping, Curling, Snowshoe, And ski-joining. In the 1930s, The first downhill ski resort, Sunshine Village, Was developed by the Brewsters. Mount Norquay ski area was also developed during the 1930s, With the first chairlift installed there in 1948. Since 1968, When the Banff Springs Hotel was winterized, Banff has been a year-round destination. In the 1950s, A Trans-Canada Highway was constructed, Providing another transportation corridor through the Bow Valley, Making the park more accessible. Canada launched several bids to host the Winter Olympics in Banff, With the first bid for the 1964 Winter Olympics, Which were eventually awarded to Innsbruck, Austria. Canada narrowly lost a second bid for the 1968 Winter Olympics, Which were awarded to Grenoble, France. Once again, Banff launched a bid to host the 1972 Winter Olympics, With plans to hold the Olympics at Lake Louise. When nearby Calgary hosted the 1988 Winter Olympics, The cross-country ski events were held at the Canmore Nordic Centre Provincial Park at Canmore, Alberta, Located just outside the eastern gates of Banff National Park on the Trans-Canada Highway. Banff National Park is in the Rocky Mountains on Alberta's western border with British Columbia in the Alberta Mountain Forests ecoregion. By road, The town of Banff is 128 kilometres, Or 80 miles, West of Calgary, And 401 kilometres, Or 249 miles, Southwest of Edmondon. Jasper National Park borders Banff National Park to the north, While Yoho National Park is to the west and Kootenay National Park is to the south. Kananiskis Country, Which includes Bow Valley Wildland Provincial Park, Spray Valley Provincial Park, And Peter Lockheed Provincial Park, Is located to the south and east of Banff. The Trans-Canada Highway passes through Banff National Park, From the eastern boundary near Canmore, Through the towns of Banff and Lake Louise, And into Yoho National Park in British Columbia. The Banff Townside is the main commercial center in the National Park. The village of Lake Louise is at the junction of the Trans-Canada Highway and the Icefields Parkway, Which extends north to the Jasper town site. The Banff-Windermere Highway extends to the south from Castle Junction, Connecting Banff National Park with Kootenay National Park and Radium Hot Springs. Lake Louise, A hamlet 54 kilometers or 34 miles northwest of the town of Banff, Is home to the landmark Chateau Lake Louise at the edge of Lake Louise. Located 15 kilometers from Lake Louise, Moraine Lake provides a scenic vista of the valley of the Ten Peaks. Lake Louise is one of the most visited lakes in the world and is framed to the southwest by the Mount Victoria Glacier. The Icefields Parkway is a 230 kilometer long, Or 140 mile road, Connecting Lake Louise to Jasper, Alberta. The parkway originates at Lake Louise and extends north up the Bow Valley past Hector Lake, Which is the largest natural lake in the park. Other scenic lakes near the parkway include Bow Lake and Pato Lakes, Both north of Hector Lake. The parkway then crosses Bowes Summit and follows the Mestalla River to Saskatchewan Crossing, Where it converges with the house and North Saskatchewan River. Bow Summit is the highest elevation crossed by a public road in Canada. The North Saskatchewan River flows east from Saskatchewan Crossing out of Banff into what is known as David Thompson Country and on to Edmondon. The David Thompson Highway follows the North Saskatchewan River, Past the man-made Abraham Lake, And through David Thompson Country. North of Saskatchewan Crossing, The Icefields Parkway follows the North Saskatchewan River up to the Columbia Icefield. The parkway crosses into Jasper National Park at Somupta Pass at 2, 035 meters or 6, 677 feet in elevation and continues on from there to Jasper Townsite. The Canadian Rockies consist of several northwest-southeast trending ranges. Two main mountain ranges are within the park, Each consisting of numerous sub-ranges. The western border of the park follows the crest of the Main Ranges, Also known as the Park Ranges, Which is also the Continental Divide. The main ranges in Banff National Park include the North to South, The Waputig, Bow, And Blue ranges. The high peaks west of Lake Louise are part of the Bow Range. The eastern border of the park includes all of the front ranges, Consisting of from north to south, Palacer, Sawback, And sundance ranges. The Banff Townside is in the Front Ranges. Just outside the park to the east lie the foothills that extend from Canmore at the eastern entrance of the park eastward into the Great Plains. Well west of the park, The western ranges of the Rockies pass through Yoho and Kootenay National Parks. Through the tallest peak entirely within the park is Mount Forbes at 3, 612 meters or 11, 850 feet. Mount Assiniboine on the Banff Mount Assiniboine Provincial Park border is slightly higher at 3, 618 meters, 11, 870 feet. The Canadian Rockies are composed of sedimentary rock, Including shale, Sandstone, Dolomite, And limestone. The vast majority of geological formations in Banff range in age from Precambrian to the Jurassic period. However, Rocks as young as the Lower Cretaceous can be found near the east entrance and on Cascade Mountain above the Banff town site. These sedimentary rocks formed at the bottom of shallow seas between 600 and 175 million years ago, And were pushed east during the Laramide Orogeny. Mountain building in Banff National Park and did approximately 55 million years ago. The Canadian Rockies may have risen up to 8, 000 meters or 26, 000 feet approximately 70 million years ago. Once mountain formations ceased, Erosion carved the mountains into their present rugged shape. The erosion was first due to water, Then was greatly accelerated by the quaternary glaciation 2. 5 million years ago. Glacial landforms dominate Banff's geomorphology, With examples of all classical glacial forms, Including cirques, Arrites, Hanging valleys, Moraines, And u-shaped valleys. The pre-existing structure left over from mountain building strongly guided glacial erosion. Mountains in Banff include complex, Irregular, Anticlinal, Synclinal, Castellate, Dogtooth, And sawback mountains. Many of the mountain ranges trend northwest to southeast, With sedimentary layering tipping down to the west at 40 to 60 degrees. This leads to dip-slope landforms, With generally steeper east and north faces, And trellis drainage, Where rivers and old glacial valleys followed the weaker layers in the rocks, As they were relatively easily weathered and eroded. Classic examples are found at the Banff town site proper. Mount Rundle is a classic dip slope mountain. Just to the north of the Banff town site, Castle Mountain is composed of numerous Cambrian Age rock formations. The uppermost section of the peak consists of relatively harder dolomite from the Eldon Formation. Below that lies the less dense shales of the Stephen Formation, And the lowest exposed cliffs or limestones of the Cathedral Formation. Dogtooth's mountains, Such as Mount Louise, Exhibit sharp, Jagged slopes. The sawback range, Which consists of nearly vertical dipping sedimentary layers, Has been eroded by cross gullies. The erosion of these almost vertical layers of rock strata in the sawback range has resulted in formations that appear like the teeth on a saw blade. Erosion and deposition of higher elevation rock layers has resulted in scree deposits at the lowest elevations of many of the mountains. Banff National Park has numerous large glaciers and icefields, 100 of which can be observed from the Icefields Parkway. Small cirque glaciers are fairly common in the main ranges, And depressions on the side of many mountains. As with the majority of mountain glaciers around the world, The glaciers in Banff are retreating. While Pado Glacier is one of the longest continuously studied glaciers in the world, With research extending back to the 1970s, Most of the glaciers of the Canadian Rockies have only been scientifically evaluated since the late 1990s. Glaciologists are now researching the glacier in the park more thoroughly. And have been analyzing the impact that reduced glacier ice may have on water supplies to streams and rivers. The largest glaciated areas include the Waputik and Wapta Icefields, Which both lie on the Bamphioho National Park border. Outlets of the Wapta Ice Field on the BAMF side of the Continental Divide include Pato, Bow, And Vulture glaciers. Bow Glacier retreated an estimated 1, 100 meters, Or 3, 600 feet, Between the years 1850 and 1953. And since that period there has been further retreat, Which has left a newly formed lake at the terminal moraine. The Columbia Ice Field at the northern end of Banff straddles the Banff and Jasper National Park border and extends into British Columbia. Snow Dome in the Columbia Ice Field is a hydrological apex of North America, With water flowing via outlet glaciers to the Atlantic, Pacific, And Arctic Oceans. Saskatchewan Glacier, Which is approximately 13 kilometers, Or 8 miles in length, And 30 square kilometers, Or 12 square miles in area, Is the major outlet of the Columbia Ice Field that flows into Banff National Park. Between the years 1893 and 1953, Saskatchewan Glacier had retreated a distance of 1, 364 meters, Or 4, 475 feet, With a rate of retreat between 1948 and 1953 averaging 55 meters or 180 feet per year. Under the Kirpin climate classification, The park has a sub-arctic climate with cold, Snowy winters and mild summers. The climate is influenced by altitude with lower temperatures generally found at higher elevations. Located on the eastern side of the Continental Divide, Banff National Park receives 454 mm or 17. 87 inches of precipitation annually. This is considerably less than in Yoho National Park on the western side of the divide in British Columbia, Where 884. 2 mm, Or 34. 81 inches, Is received at Wapita Lake and approximately 1, 282 mm, Or 50. 5 inches, At Boulder Creek annually.
