Are there any articles about Banff, a Canadian tourist resort?

Banff National Park is the oldest national park in Canada, built in 1885, located in the Canadian Rocky Mountains. Located at120km (80 miles) west of Calgary, Alberta, the park includes 664 1 km2 of mountains, with numerous glaciers and ice fields, dense coniferous forests and alpine landscapes. Icefield Park Avenue extends from Lake Louis and connects to Jasper National Park in the north. There are provincial forests and Yoho National Park in the west, Kootenay National Park in the south and Kananaskis National Park in the southeast. The main business center of the park is Banff Town, located in the Bow Valley.

Canada Pacific Railway played an important role in Banff's early years, building Banff Hot Springs Hotel and Lake Louis Castle, and attracting tourists through a large number of advertisements. At the beginning of the 20th century, Banff built roads, sometimes by war detainees, and sometimes through public works projects during the Great Depression. Since the1960s, the park accommodation facilities have been open all year round, and the annual number of tourists to Banff increased to more than 5 million in the1990s. Millions of people pass through parks on the Trans-Canada Highway. Because Banff is one of the most visited national parks in the world, the health of its ecosystem is threatened. In the mid-11990s, Canadian parks responded by launching a two-year study, which put forward management suggestions and new policies aimed at protecting ecological integrity.
