Emerald Lake (British Columbia)
|Location||Yoho National Park, British Columbia|
|Primary outflows||Emerald River|
Emerald Lake is located in Yoho National Park, British Columbia, Canada. Yoho National Park is one of the 4 contiguous National Parks in the heart of Canada's Rocky Mountains, along the boundary of British Columbia and Alberta Provinces, the other Parks are Kootenay, Jasper, and Banff. Many Provincial Parks, having near-similar environmental protection and as-spectacular nature, also join these federal reserves. Emerald Lake Lodge, a high-end lodge or hotel, is on a peninsula jutting into the lake, it was founded in the 1920's and completely re-built in the 1980's. A quiet 2 lane paved road about 15 km / 9 miles long connects the busy Trans-Canada Highway with Emerald Lake, the exit is well marked. A 5.2 km (3.2 mi) hiking trail circuits the lake, the first half of which is accessible to wheelchairs and strollers, many other more advanced hiking trails go in different directions up into the mountains, be sure to be well prepared in skill, fitness and in hazard awareness before venturing onto them. Many wild animals live in the area and are protected by Park Law, Brown (Grizzly) Bears and Black Bears are fairly common, they co-exist quite well with humans as the Park has strict laws on garbage control and good advice to Park Visitors on practicing bear safety and being "Bear Aware". Mountain Goats and Bighorn Sheep are seen at higher altitudes, and many smaller mammals are common everywhere. Hunting is strictly prohibited in the Park, fishing is permitted with a Park license. During the summer months, canoe rentals are available from the Lodge, in the winter, the lake is a popular cross country skiing destination. Canada's National Parks do not permit private or business land ownership within their boundaries, all development is strictly controlled by the National Park for environmental preservation, development permits are rarely if ever given, and then only after extensive Gov't review and consultation, the land the business occupies is leased from the Park, nearly all businesses in the Parks were established decades ago, and current approval is exceedingly rare. There is a strict "need-to-reside" law in place for living in a Canadian Mountain National Park town or village, simply put you must prove you need to live there for reasons of operating a Park-approved business or service, unless you are a non-management employee. The railway and timber town of Golden BC is the nearest town to Emerald Lake that is outside the Park boundaries, it is about 50 km / 30 miles distant to the west, and has many lodging options, the small historic railway village of Field is in Yoho Park near the highway exit to Emerald Lake, and has a large Park-operated Information and Visitor's Center, Field Village also has gas, food and B & B's. The Park Service Center of Lake Louise, which has limited lodging, is about 30 km / 20 miles to the east of Emerald Lake in Banff National Park, while the famous Town of Banff is about 60 km / 40 miles east of Lake Louise. Vehicle / RV campgrounds are common throughout the region for summer use.
Emerald Lake is enclosed by mountains of the President Range, named after the President and Vice-President of the coast to coast Canadian Pacific Railway, built in 1885 and which runs through Yoho National Park. Other peaks are Mount Burgess and Wapta Mountain. The Emerald Basin opens to the west and traps rain and snow storms, causing frequent rain in summer and heavy snowfalls in winter. This influx of moisture works with the lake's elevation of 1200 meters / 4400 feet above sea level to produce a unique selection of flora. Trees found here are more typical of B.C.'s wet interior forests of the Columbia Mountains immediately to the west, such as western red cedar, western yew, western hemlock and western white pine. The alluvial fan on the northeast shore produces wildflowers in abundance during late June and early July.
Due to its high altitude, the lake is frozen from November until May. The vivid green color of the water is caused by powdered rock from the glaciers which reflects the blue-green spectrum of sunlight, the rock type and amount in the water causes the color to vary from lake to lake and month to month. It is most spectacular in July and August as the glaciers containing the sediment melt somewhat in the summer heat, in Spring and Autumn the water is clearer.
The first non-indigenous person to set sight on Emerald Lake was Canadian guide Tom Wilson, who stumbled upon it by accident in 1882. A string of his horses had gotten away, and it was while tracking them that he first entered the valley. The lake had an impression on even the most seasoned of explorers: "For a few moments I sat [on] my horse and enjoyed the rare, peaceful beauty of the scene." It was Wilson who gave the lake its name because of its remarkable color, which due to a different rock type producing the sediment suspended in the glacial water tends to reflect the green spectrum rather than the blue spectrum seen in Moraine, Hector, Bow and Peyto Lakes in neighboring Banff National Park. However, this was not the first time Wilson had dubbed a lake 'Emerald'. Earlier that same year he had discovered another lake which he had given the same moniker, and the name even appeared briefly on the official map. This first lake however, was shortly renamed Lake Louise.
