In 1883, on the Canadian Rocky Mountains, three railway workers discovered a natural hot spring, and from there the park was born. Nowadays, it is one of the world's popular tourist spots with great mountain scenery. Every year, millions of people visit it for its wonderful views.Banff National Park is part of UNESCO's Canadian Rocky Mountain World Heritage site. Located in the heart of the Canadian Rockies, the park has perfect mountains like those on postcards. They are from 45 to 120 million years old, with the highest in the park, Mount Forbes, coming in at 11,850 feet.Banff National Park is 80 miles west of Calgary. Calgary's international airport is serviced by major national and international carriers with many flights arriving daily. Open year-round, it offers amazing wildlife viewing and sightseeing, plus many shopping and dining choices, any time of the year. Summer is popular for hiking, mountain biking and cycling, photography, and climbing. The best time for viewing the seasonal color is fall, when the trees turn yellow.In winter, the mountain makes exciting downhill (速降) and cross-country skiing. In fact, three major downhill ski resorts (度假胜地)operate within the park. Lake Louise Ski Resort, Sunshine Village, and Mount Norquay combine to offer a large area for skiing, not to mention the backcountry trails available throughout the park. The ski season, which runs from November to May, is one of the longest in North America. Visitors can also enjoy wildlife tours, ice walks, and dogsleds (雪橇)．Weather in the Canadian Rockies can change quickly. A single day can have a mix of sunshine, snow, wind, and rain, so you should change your clothes. In summer, temperatures average a high of 70(21 ℃), and daylight lasts until 11 p．m. Autumn brings cool nights and fresh air. Winters can be very cold. In January, the average temperature is 7 ℃ below zero, but by April it is 9 ℃.【语篇解读】本文是一篇说明文。
