Thirty Mile (Yukon River)

Thirty Mile (Yukon River)


Natural Heritage

At 3,200 km, the Yukon River is the tenth-longest river in the world and the fourth longest in North America. The “Thirty Mile” is a relatively narrow (50-100 metre wide) river channel comprising a 48 km segment of the river in south-central Yukon. The section begins at the outflow of Lake Laberge, 96 km north of Whitehorse, and ends at the confluence of the Teslin River.

With its crystal clear waters, deeply incised tributary channels, slumping and undercut river banks and almost perpendicular sand and gravel bluffs nearly 100 metres high, this is perhaps the most scenic segment of the Yukon River. The Thirty Mile’s blue-green waters are important to the river’s salmon migration.

White volcanic ash in the river banks was deposited over the southern Yukon region by a major eruption more than 1,200 years ago. Other interesting geological features such as moraines and eskers provide evidence of glaciation. Wolverines, grizzly bears, bald and golden eagles, and trumpeter swans prowl the river and its banks, which are also home to large populations of migrant birds.

Cultural Heritage

From prehistoric times until the late 1950’s, when all-weather roads were first built and air travel became common, the Yukon River was the region’s highway for settlement and development, and the nomination of the Thirty Mile to the CHRS was based largely on its close connection with the famous Klondike gold rush and paddle-wheeler eras on the Yukon River. At its peak in 1898, the Klondike gold rush saw nearly 30,000 gold seekers in 7,000 boats travel the Thirty Mile en route from Bennett, B.C. to the goldfields near Dawson City. The Thirty Mile was the most difficult part for the run between Whitehorse and Dawson City. Its strong current, shifting shoals and treacherous rocks claimed more ships than any other stretch of the Yukon River. Simply marked gravesites are found along the Thirty Mile, and some locations are named after the boats that were wrecked there, such as Domville Creek, Casca Reef, La France Creek, and Tanana Reef.

Recreational Heritage

With scenic views and fascinating historical artifacts from the Klondike era, Thirty Mile attracts many paddlers and boaters. Each year many river tourists travel the Thirty Mile in canoes, kayaks, power boats and rafts between Whitehorse and Carmacks or Dawson City seeking to re-create the experience of the gold seekers while enjoying Yukon wilderness. Yukon Parks maintains campsites and facilities along Thirty Mile through a partnership with Ta’an Kwäch’än First Nation. There is good camping, with plenty of water and firewood. The best sites are Johnston Island and Hootalinqua.

Viewing and photographing Yukon wildlife and hiking up nearby hills for views of the river are favourite activities, as are visiting historic ruins and fishing for migrating salmon, grayling, northern pike, lake trout, whitefish and inconnu.

Who Manages the River?

The Thirty-Mile River is managed by the Yukon Government. Yukon Parks and Yukon Tourism and Culture’s Historic Sites Unit and Tourism Branch all have responsibilities for the river. The management plan for the river and the ten-year report on the designation are available online.

The Ta’an Kwach’an Council also protects and promotes sites within the river corridor that are part of and contribute to their values and cultural heritage.

Fun Fact:

The name Yukon comes from the Gwich’in word Yu-kun-ah meaning “great river” and is a reference to the Yukon River.

Shipyard (Hootalinqua) Island is associated with the gold rush era and is still occupied by the S.S. Evelyn/Norcom, a paddlewheeler built in 1908 that has been slowly disintegrating there since being hauled to this winter storage facility at the end of the 1913 shipping season.
