The icefield is subject to both maritime polar air masses from the west, bringing cyclonic storms between September and June, and continental polar air masses from the east, particularly during winter (Reference HeusserHeusser, 1956; Reference HenochHenoch, 1971). Mountaineers will make use of informal bivi's on or near the glaciers. The environmental and economic importance of the Columbia Icefield, in addition to its relative ease of access, has drawn people to document changes of its outlet glaciers for more than 100 years. (a) Systematic bias with slope in the 1966 elevation data. This category has the following 143 subcategories, out of 143 total. Previous studies on glaciers of the Columbia Icefield primarily focused on the retreat of the main glaciers, Athabasca, Columbia and Saskatchewan, and some of the smaller glaciers, such as Dome, Manitoba, Stutfield and Boundary glaciers, from the mid-19th century to the 1970s. The area can get as much as much as 10 m (33 ft) of snow each year. The distributions of elevation change of the Columbia Icefield are approximated by a Gaussian curve. Numa Pass - the trail-head is a short distance south of Parker Ridge and leads to a very popular back-country hiking route called the Brazeau Loop. The elevation points were also divided into the flowsheds for analysis. Fig. Over the period 19192009, glaciers on average retreated 1150 34 m and shrank by 2.4 0.2 km2. Weber, Melissa Sharp, Martin If you plan to hang around in the area for a few days, it's best to stock up before you leave Banff or Jasper. The average elevation of the ice field is about t.). Large outlet glaciers experienced the greatest absolute ice loss, while small, detached glaciers lost the most relative length and area. Accumulation season temperatures are highly variable for most periods and follow similar trends for maximum, mean and minimum temperatures. 4). and Pelto, B. The Columbia Icefield has a human history that is unique compared to the rest of the mountain ranges and most places throughout North America. We added an additional error term for offset between the IBCS maps (24 m) and snow cover in the 1979 photographs (5 m). 6f)) have few elevation bands where both debris-covered and bare ice exist, so debris-dependent elevation changes are difficult to establish. The snowline and debris cover were also digitized where present. The download should start shortly. Fig. ashx?id=15f028db-a6f9-4ae8-9b14-802ad013844c). 6e). We modified the extents of the flowsheds to include the 1919 glacier extents and to separate a few glaciers into individual flowsheds. 6). Glacier changes of the Columbia Icefield. Linking Lake Louise with Jasper, Alberta is one of the most beautiful journeys on the planet - the Icefields Parkway.. Chun, Kwok P. Melting snow and ice feed rivers that drain into the Atlantic, the Pacific and the Arctic Oceans. Glaciers with debris-covered sides experienced the greatest ice loss, but they are also the largest outlet glaciers. Such options can only be found in Jasper, Lake Louise or Banff. While the town of Lake Louise is barely more than a collection of hotels and restaurants it is an amazing basecamp from which to explore the most picturesque and stunning landscapes in the Canadian Rockies. Prior to our study, elevation and volume change estimates are only available for Saskatchewan, Athabasca and Columbia glaciers. Arendt, Carli A. The 3,000 m (9,800 ft) descent from the summit lasted 50 km (31mi) and became the longest continuous ski run at that point in Canadian history. Ablation season temperatures are known to have a strong influence on glacier change in a continental climate (Reference Bitz and BattistiBitz and Battisti, 1999; Reference BolchBolch, 2007; Reference Hoffman, Fountain and AchuffHoffman and others, 2007; Reference Koch, Menounos and ClagueKoch and others, 2009; Reference MooreMoore and others, 2009). The numbers refer to the flowsheds listed in Table 1. Thinning rates under debris cover differ according to the thickness of debris. Spence, Christopher The rates of elevation and volume loss decreased between 2000 and 2009. Some of the popular destinations from Jasper include the beautiful Maligne Lake, the Columbia Icefield, the stunning Athabasca Falls, as well as countless hikes and trails around the town. This pattern is evident on glaciers with debris-covered sides, such as Athabasca Glacier (FS5) and Castleguard IV (FS14; Fig. Brown, Sarah A 2.5 m resolution orthoimage was also created for 2009 using the rectified SPOT 5 images and the DEM. Slow down while driving the Icefields Parkway - be it for going downhill, other tourists, slow RVs and buses, the wildlife, the road conditions - or for the frequent speed reductions often with speed traps. Total volume change for the Columbia Icefield was determined by summing volume change from all of the flowsheds for each period. Glaciers of the Columbia Icefield have a delayed response to climate forcing, indicating the need for long glacier records to determine relations with climate. This makes that point, the summit of Snow Dome, one of only 2 hydrologic apexes in North America. The Icefields Parkway ( French: Promenade des Glaciers ), is a 230 km (140 mi) long scenic road that parallels the Continental Divide, traversing the rugged landscape of the Canadian Rockies, travelling through Banff National Park and Jasper National Park. A 200 m grid was used in the accumulation area and on snow cover where there is low contrast and elevations are more difficult to determine. Icefields Parkway Map Coverage The Icefields Parkway Map covers the entire length of the Icefields Parkway, a 232-kilometre (144-mile) route between the village of Lake Louise and the town of Jasper. These glaciers not only advanced, but increased in area, thickened and gained volume during the 1970s. The Athabasca Glacier is just one component of the huge Columbia Icefields above these mountains, which straddle the Alberta-British Columbia boundary, and whose waters end up flowing to the . Values are calculated from 1999 and 2009 data. The Columbia Icefield is about 325km2 (125sqmi) in area and is the largest region of ice and snow in mainland North America south of the Arctic Circle. Meanwhile, supraglacial ponds and streams expose ice and enhance melt, increasing thinning. Carey, Sean K. and At low elevation, the region is characterized by an EngelmannSpruceSubalpine Fir ecosystem, giving way to alpine tundra above 2250 m a.s.l. Douglas proceeded to name a nearby mountain of similar height as Mount Hooker, after his expeditions sponsor. To determine glacier lengths, flowlines were digitized from the highest point of the glacier, down to the center of the glacier terminus, perpendicular to the contours (Reference PaulPaul and others, 2009). We determined length, area, elevation and volume change of the Columbia Icefield using Interprovincial Boundary Commission Survey maps from 1919, eight sets of aerial photographs from 1948 to 1993, and satellite data from 1999 to 2009. and The critical thickness ranges between 0.01 and 0.09 m and depends on the lithology, condition (wet or dry), continuity of the debris cover, and meteorological conditions (Reference Mattson, Gardner and YoungMattson and others, 1993; Reference Brock, Mihalcea, Kirkbride, Diolaiuti, Cutler and SmiragliaBrock and others, 2010). We use sequential analysis of glacier extents and elevation data to calculate length, area, elevation and volume changes of glaciers of the Columbia Icefield, including accumulation areas. From here you can admire the Athabasca glacier and the mountains that make up the eastern edge of the Columbia Icefield with Mount Athabasca and Snow Dome dominating the western skyline . 195570). We ran a block adjustment to rectify the photographs and produced an exterior orientation file to create reference stereo models. For details, read our story: Hiking Parker Ridge. Much like Bow Lake, you can park right alongside Waterfowl Lakes and walk to the water in just a few short steps. Douglass encounter with the giant mountains was in 1827 as he was crossing the Athabasca Pass. However, the up-glacier extent of the debris cover changed little while debris-covered termini retreated between 1993 and 2009, thus reducing the debris-covered area. Rates of glacier change in these two periods are near zero, as ice loss decreased and some glaciers advanced, increased in area, thickened and gained volume. icefield located in the Park Ranges of the Canadian Rockies in Alberta and British Columbia, Hostelling International's Hilda Creek Hostel, https://en.wikivoyage.org/w/index.php?title=Columbia_Icefield&oldid=4638080, Creative Commons Attribution-ShareAlike 3.0 Licensed. Total ice cover was 216 km2 in 2001 (Reference Bolch, Menounos and WheateBolch and others, 2010). Contrast in the snow-covered accumulation areas was poor for the 1948 and 1955 photographs, but satisfactory for other years. A combination of reduced ice flux from the icefield and strong negative mass balance at the surface can produce high thinning rates and high absolute ice losses. Parts of the trail are quite high elevation and there is a possibility of seeing caribou and other wildlife like grizzly bears, hopefully at a safe distance. We averaged the data over the icefield and calculated the mean annual, ablation (MaySeptember) and accumulation (OctoberApril) season temperatures and total annual, ablation and accumulation season precipitation. This page shows the elevation/altitude information of Columbia Icefields Tour, Division No. Our total volume loss for the period 191979 is 0.97 0.45 km3. Driving an ice dynamics model with dynamically downscaled meteorological fields obtained from general circulation models provides one avenue to better understand how glaciers that form the Columbia Icefields will likely change in the future. Water from the Columbia Icefield and its glaciers makes up underground rivers and caves and flows to three different oceans. Rates of ice loss are related to changes in annual precipitation that occurred 47 years earlier and annual temperature that occurred 3 years earlier. The average elevation of the Icefield is about 3,000 m with Mt Columbia being the highest point (and the highest point in Alberta) at 3,747 m (about 12,300 ft). Saskatchewan Glacier (FS10) lost the greatest volume (2.8 1.2 km3 w.e. We extracted monthly minimum, mean and maximum temperatures, as well as precipitation, from 1919 to 2009 from the ClimateWNA v.4.62 program, which can be downloaded at http://www.genetics.forestry.ubc.ca/cfcg/ClimateWNA/ClimateWNA.html. Lake Louise and Banff are about 1 hr 45 minutes and about 2.5 hours south, respectively. Elevation change rates of debris-covered and bare ice for glaciers with (a, b) debris-covered sides and (cf) debris-covered termini. Mean elevation change over periods with the 1919 data were calculated for these flowsheds using available 1919 elevation points. Reference BolchBolch (2007) reports stronger area retreat of Tuyuksu glacier, northern Tien Shan, after the late 1970s. Rates of change of (a) length, (b) area, (c) elevation and (d) volume over each period from 1919 to 2009. Lewis, John L. Surface air temperature affects the intensity of surface melt for glaciers, but it represents only one term in the energy budget affecting the surface of a glacier. 4. In order to create a comparable dataset for each flowshed, we calculated the rate of glacier change over the new period (e.g. A moderate day hike will take you to the toe of that glacier and back to the road. Over 150 000 points were collected in total. id=15f028db-a6f9-4ae8-9b14-802 ad013844c), compared with cumulative net geodetic balance of glaciers of the Columbia Icefield from 1966 to 2009. Leg 4: 39 miles (1100 feet up, 2000 feet down) Bow Pass, 6785 feet, is the highest elevation on the Icefields Parkway. Both maximum and mean ablation season temperatures increased following 1979. These patterns influence the temperatures and paths of winter storm systems that bring the majority of precipitation to western North America and have been linked to changes in glacier mass balance (Reference Bitz and BattistiBitz and Battisti, 1999; Reference Dyurgerov and MeierDyurgerov and Meier, 2000; Reference Demuth and BonardiDemuth and others, 2008). He loves discovering the wild and remote places of this park, and while hed rather be in the mountains, theres no internet access there. The Columbia Icefield, in the Canadian Rocky Mountains, plays a significant role as a water resource because it is situated on a triple water divide. We lack measurements of debris thickness, but the observed elevation change rates provide some insight into the relative thickness and distribution of debris (Fig. However, at higher elevations the rates between debris-covered and bare ice are similar, and in some cases (e.g. On individual glaciers, the difference between thinning rates of debris-covered ice and bare ice is greatest on glaciers with debris-covered sides (e.g. On stable bedrock or stationary boulders, free of vegetation and snow, we collected 2236 GCPs from the 1986 stereo models to rectify the other seven years of photography. Dawson, Jackie Glaciers with debris-covered termini lost less length and area, but more elevation than clean ice glaciers. 7. Parker Ridge - the trail-head is about 10 km south of the Icefield Centre close to the Hilda Creek Hostel. Before the collision of the North American plate with the tectonic plates under the Pacific Ocean, Alberta was actually located in the coastal regions of North America. 7ac). We included aerial photographs from 1948, 1955, 1966, 1970, 1974, 1979, 1986 and 1993 to supplement the geodetic data contained in the interprovincial maps (Table 2). Rates of elevation and volume change are also correlated with ablation season precipitation over periods lagged 56 years (r = 0.80, p < 0.01). Ablation season precipitation anomalies are less variable than accumulation season and annual precipitation anomalies. Groulx, Mark From the aerial photographs, we could see that the coverage of debris differed considerably, and supraglacial streams and ponds were present on some of the glaciers. Minimum ablation season temperature generally increased between 1919 and 2009. Menounos, B. ), respectively, were calculated by combining the length or area error terms from the early year (E Where E There's nothing here that would pass for night life. Groulx, Mark The general pattern of glacier change in the 20th century observed at the Columbia Icefield is one of rapid ice loss from the 1920s to the 1950s, followed by reduced ice loss in the 1960s and 1970s, and ending in renewed large losses during the 1980s and 1990s. A few of the small glaciers with debris-covered termini (e.g. As radar can penetrate winter snow cover over glaciers, the DEM is representative of the ablation surface at the end of the 1999 ablation season (Reference Schiefer, Menounos and WheateSchiefer and others, 2007). and lost 14.3 2.0 km3 w.e. Kendall, Rachel A. Using Eqn (1), we included a 0.5 m w.e. 2020. Outlet glaciers have greater absolute ice losses, but lower relative losses than detached glaciers. The average elevation of the Icefield is about 3,000 m with Mt Columbia being the highest point (and the highest point in Alberta) at 3,747 m (about 12,300 ft). Within the outlet glacier group, icefall outlet glaciers lost more ice than the non-icefall outlet glaciers. Properties of glaciers of the Columbia Icefield by flowshed, where, Data used for glacier change analysis (AP = aerial photograph), Error estimates used in the glacier analysis. It's just across the road from the centre and you can walk or drive to that parking lot. Glaciers of the Columbia Icefield retreated a mean distance of 1150 34 m and decreased in area by 2.4 0.2 km2 on average between 1919 and 2009. This is the largest ice field in the Rockies at 325 kilometers squared, and it gets around 275 inches of snow every year. Bighorn sheep are regulars on the glaciers of the Columbia Icefield, while mountain goats prefer the rocks of the alpine peaks and cliffs. Feature Flags: { Bonsal, Barrie The drive along the parkway is one of the most scenic drives in the world. Rates of change of (a) length, (b) area, (c) elevation and (d) volume over each period from 1919 to 2009. Total area loss was 59.6 1.2 km 2 (23 5%), and mean elevation change was 49 25 m w.e., resulting in a total volume loss of 14.3 2.0 km 3 w.e. Errors in length and area change (E Much of the landscape here is pretty bleak. The glaciation of the Pleistocene created the topography of the mountains in the icefield and the most recent glacial maximum has yet to retreat from the mountain range. Waterfowl Lakes are about 10-15 minutes past Peyto Lake, on the Icefields Parkway, and are just as gorgeous and blue as both Bow and Peyto. Hike one of the trails in the area, like the Wilcox Pass Trail. 3b). Cardinal Systems provided licensing and support for their VR Mapping photogrammetry software. the six outlet glaciers from the Columbia Icefield are within a short distance of the Parkway, and thereby, can be easily accessed. Absolute retreat, shrinkage and volume loss are greatest for large glaciers (3050 km2), whereas relative retreat and area loss have the opposite trend and are greatest for small glaciers (<1 km2). Brardinoni, F. Mean and total values represent icefield-wide changes. The flowsheds are from glacier drainage basins in the western Canada glacier inventory, created through hydrological analysis of DEMs, detailed in Reference Bolch, Menounos and WheateBolch and others (2010). A fascinating phenomenon occurs that allows the rosy finch to thrive upon the glacier. Aciego, Sarah M. Parks Canada may have a small area of the glacier roped off where you can get onto the ice where it is safe. These were to be among the tallest peaks in the Rocky Mountains and North America, measuring between 4575 m and 5183 m (15,000 ft and 17,000 ft) tall as reported by David Douglas in 1827. Be cautious. We found that glacier volume change rates were correlated with elevation. The whiskers represent the data extremes (5th and 95th percentile), and the circles are outliers (data outside the 5th and 95th percentiles). The mountains of the Columbia Icefield are generally made of thick slabs of limestone and dolomite that cracked and were then stacked on top of the younger Cretaceous sandstone and shale. 3) to account for changes in the density profile (Reference Andreassen, Elvehy and KjllmoenAndreassen and others, 2002; Reference Cox and MarchCox and March, 2004) and a 5 m w.e. Lying on a wide, elevated plateau, it is the largest icefield in the Canadian Rockies. Mount Columbia is the tallest mountain in Alberta and is only second to Mount Robson for elevation and prominence in the Rocky Mountains. Starting at an elevation of 2040 m (6,691 ft), this trail begins at a higher elevation than many trails in the Rocky Mountains finish at. If you are taking the glacier bus tour, you will park at the centre and join the crowds on the buses provided. and Thinning rates of debris-covered ice were 3060% lower than those for clean ice. 6. Scan the QR code to download PeakVisor mobile app, Adventures and Attractions in the Columbia Icefield, PeakVisor 3D Map and identify its summits. Over nine decades, the Columbia Icefield shrank by 59.6 1.2 km2, thinned by 49 25 m w.e. There is a general decreasing trend in precipitation from 1948 to 1970 and after 1993 (Fig. We use necessary cookies to make the website work, also they are used to understand site usage and make improvements. Lemieux, Christopher J. The area can get as much as much as 10 m (33 ft) of snow each year. The Columbia Icefield is the largest icefield in the Canadian Rockies and covers around 230 sq km (89 sq mi) at depths up to 265 meters (1,200 ft). The hikers' subreddit. By dividing both volume estimates by the areas they represent (i.e. From 1948 to the 1970s, rates of ice loss decreased and some glaciers advanced and thickened. Mount Columbia is also the second tallest of the famed 11,000ers of the Canadian Rockies. The eastern side of the ice field is reached by paved highway from Banff, 100 miles (160 km) south, and from Calgary, another 80 miles (130 km) away to the southeast. 2021. Huang, J. The town of Jasper was established as Jasper House in 1813 as a fur trade outpost. Reference Reynolds and YoungReynolds and Young (1997) calculated a total volume loss of 0.23 km3 in the ablation area of Athabasca Glacier (excluding debris cover) between 1919 and 1979. The majority of glaciers face north to east. Those photographs have late-lying snow which can obscure glacier extents. Nothing in the way of supplies is available at the Icefields Centre. Elevation change rates have the highest correlation with annual precipitation anomalies over periods lagged 4 years (r = 0.855, p < 0.01).Volume change rates also have the highest correlation with annual precipitation anomalies, but lagged over periods lagged 5 years (r = 0.860, p < 0.01). Our rates of glacier change show moderate correlations (r = 0.24 to r = 0.47) with the PDO (data from N.J. Mantua, http://jisao.washington.edu/pdo/), but none were significant. The tourist main destination at the Columbia Icefield is the Icefield Discovery Centre. There are two short trails that start from the Icefield Discovery Centre, one of which leads through the scree field in front of the glacier, while the other leads to the toe of the Athabasca Glacier. Elevation: 3 747 m Glaciers: 62 Area: 214.2 km 2 22 mountains By Prominence Mount Columbia 3 747 m (prom: 2 380 m) North Twin Peak 3 684 m (prom: 913 m) Twins Tower 3 627 m (prom: 543 m) South Twin Peak 3 580 m (prom: 345 m) Mount Bryce 3 507 m (prom: 1 239 m) Mount Kitchener 3 505 m (prom: 331 m) Mount Athabasca 3 491 m (prom: 689 m) Snow Dome Error estimates used in the glacier analysis. Annual thinning rates below debris-covered ice are generally 3060% lower than on bare ice, especially at low elevations (Fig. ), whereas FS8 lost the least volume (0.02 0.02 km3 w.e.). There are few choices in this part of the park. Distance 5.9 km Elevation 250 m User Ratings Overall Rating 9.9 Physical Difficulty Easy (Circle) Technical Difficulty Easy (Circle) Read Reviews Directions to Trailhead Google Maps Apple Maps Hiking up Parker Ridge unlocks some amazing views of the Saskatchewan Glacier, the largest of the Columbia Icefield's six valley outlet glaciers. Glacier change is strongly related to annual temperature and precipitation. Mount Columbia (12,293 ft) is the second-highest peak in the Canadian Rockies and an iconic ski mountaineering objective. Glaciers also rapidly retreated in the Premier Range in the Columbia River watershed during this time (Reference Luckman, Harding and HamiltonLuckman and others, 1987). Debris-covered or avalanche-fed glaciers, for example, can be disconnected from climatic inputs and will respond differently from clean or outlet glaciers (Reference Granshaw and FountainGranshaw and Fountain, 2006; Reference Hoffman, Fountain and AchuffHoffman and others, 2007). While he did not discover the giants, he travelled the Continental Divide between Banff and Jasper, mapping and following the route that would later become the scenic Icefield Parkway (Highway 93). Ablation adjustments from Gulkana Glacier, Alaska, (Reference Cox and MarchCox and March, 2004) are no greater than 0.5 m, which falls within our calculated error for the elevation data. Our area changes for Columbia Icefield glaciers within this watershed over similar periods are only 4% and 10%, respectively. Reference Bolch, Menounos and WheateBolch and others (2010) reported an increase in the rate of area loss from 2000 to 2005. It was named "The Crossing", when travellers and fur traders used this spot to cross the North Saskatchewan River on their way to British . Osborn, G.D. The greatest thinning occurred at mid-glacier 1919 positions, along the center flowline (Fig. Enter the following coordinates into your GPS unit: Latitude 5213'10.8"N and Longitude 11713'41.6"W. Open in Google Maps Columbia Icefield Adventure and Skywalk guest parking. As an area becomes glaciated, the glaciers will destroy all the flora from the area and generally make it inhospitable for wildlife to live in the region. Boluk, Karla We extracted data on a 1 km grid encompassing the Columbia Icefield. surface elevation changes of five icefields in a remote region of southwest British Columbia, Canada, between the mid-1980s and 1999. While it gets busy in the summer, Jasper is not as busy as the national parks to the south. Boxes represent the first and third quartiles with the horizontal black line as the median. Glacier changes of the Columbia Icefield. Due to its elevation, most times the temperatures are significantly cooler compared to nearby towns and attractions, at lower elevations. Preliminary differences betwe en the DEMs in ice-free and . Has data issue: false The Rocky Mountains started forming about 75 million years ago and were forming until about 40 million years ago, when the Kula Plate and North American Plate stopped their collision. Glaciers include individual ice bodies and outlet glaciers, some of which have significant icefalls and are fed by avalanching (Table 1). There are restaurants that serve fine foods and stay-packages that include private access to the glacier in the morning and private access to the glacier skywalk in the evening. The Icefields Parkway started as a single lane gravel road and was later upgraded to a multilane paved highway. Be a superhero of outdoor navigation with state-of-the-art 3D maps and mountain identification in the palm of your hand! The observed steepening of the glaciers, for example, would have changed the average shortwave energy received by the glaciers over the period 19192009. and All glacier changes were significantly correlated with each other (p < 0.01), with r values ranging from 0.54 to 0.82. Close this message to accept cookies or find out how to manage your cookie settings. The water can expose ice (Reference LuckmanLuckman, 1986), enhancing ablation especially on exposed ice cliffs. We found that annual and accumulation season precipitation anomalies had significant correlations with rates of elevation and volume change, and annual temperature anomalies had significant correlations with rates of length and area change. Precipitation increased again from 1986 to 2000, before decreasing during the period 200009. The average root-mean-square errors (RMSEs) in the easting (x) and northing (y) of the three map sheets are, respectively, 17.5 and 13.5 m, yielding a total RMSE of 22.1 m. Table 2.
