Helmcken Falls, British Columbia-Canada

Helmcken Falls is a 141 m (463 ft) waterfall on the Murtle River within Wells Gray Provincial Park in British Columbia, Canada. The protection of Helmcken Falls was one of the reasons for the creation of Wells Gray Provincial Park in 1939.

Helmcken Falls is the fourth highest waterfall in Canada, measured by total straight drop without a break. Higher Canadian waterfalls are Hunlen Falls in Tweedsmuir Provincial Park, Takakkaw Falls in Yoho National Park, and Della Falls in Strathcona Provincial Park, all in British Columbia.

There are six other waterfalls on the Murtle River, upstream from Helmcken Falls. The others are The Mushbowl, Dawson Falls, Majerus Falls, Horseshoe Falls, Meadow Falls and McDougall Falls. Only Helmcken, The Mushbowl and Dawson can be reached by road. Majerus, Horseshoe and McDougall Falls are accessed by trails . Meadow Falls is very difficult to view, except by air.

Helmcken Falls was discovered in 1913 by Robert Lee, a land surveyor working for the British Columbia government. He was so impressed with the waterfall that he wrote a letter from his remote camp to Sir Richard McBride, Premier of British Columbia, requesting that the falls be named "McBride Falls". Three weeks later, Lee received a reply from the Premier stating that the waterfall was instead to be called Helmcken Falls. This name honoured John Sebastian Helmcken, a physician with the Hudson's Bay Company who arrived in Victoria in 1850. He helped bring British Columbia into Canadian Confederation in 1871. Dr. Helmcken died in 1920 at the age of 95, but never actually saw the falls himself.

Wells Gray Provincial Park is a large wilderness park located in east-central British Columbia, Canada. The park protects most of the southern, and highest, regions of the Cariboo Mountains and covers 5,250 square kilometres (524,990 hectares or 1.3 million acres). It is British Columbia's fourth largest park, after Tatshenshini, Spatsizi and Tweedsmuir.

British Columbia ⁱ/ˌbrɪtɪʃ kəˈlʌmbiə/ (B.C. or BC) (French: la Colombie-Britannique, C.-B.) is the westernmost of Canada's provinces and is known for its natural beauty, as reflected in its Latin motto, Splendor sine occasu ("Splendour without Diminishment"). Its name was chosen by Queen Victoria in 1858. In 1871, it became the sixth province of Canada.

Canada ( /ˈkænədə/) is a North American country consisting of ten provinces and three territories. Located in the northern part of the continent, it extends from the Atlantic Ocean in the east to the Pacific Ocean in the west, and northward into the Arctic Ocean. Spanning over 9.9 million square kilometres, Canada is the world's second-largest country by total area, and its common border with the United States is the longest land border in the world.

The land that is now Canada has been inhabited for millennia by various groups of Aboriginal peoples. Beginning in the late 15th century, British and French expeditions explored, and later settled, along the region's Atlantic coast. France ceded nearly all of its colonies in North America in 1763 after the Seven Years' War. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces and territories and a process of increasing autonomy from the United Kingdom. This widening autonomy was highlighted by the Balfour Declaration of 1926 and reaffirmed by the Statute of Westminster of 1931, which declared self-governing dominions within the British Empire to be equal. The Canada Act of 1982 finally severed the vestiges of legal dependence on the British Parliament.

A waterfall is a place where water flows over a vertical drop in the course of a stream or river. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf.

North America is a continent wholly within the Northern Hemisphere and almost wholly within the Western Hemisphere. It is also considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea.

North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), about 4.8% of the planet's surface or about 16.5% of its land area. As of July 2008, its population was estimated at nearly 529 million people across 23 independent states. North America is the third-largest continent in area, following Asia and Africa, and the fourth in population after Asia, Africa, and Europe.
